<h2>Fizikai dió - magvak (Jatropha curcas)</h2> <h2>Ár egy csomag 3 magot.</h2> Jatropha curcas is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to the American tropics, most likely Mexico and Central America.[2] It is originally native to the tropical areas of the Americas from Mexico to Argentina, and has been spread throughout the world in tropical and subtropical regions around the world, becoming naturalized or invasive in many areas.[3] The specific epithet, "curcas", was first used by Portuguese doctor Garcia de Orta more than 400 years ago.[4] Common names in English include physic nut, Barbados nut, poison nut, bubble bush or purging nut.[3] In parts of Africa and areas in Asia such as India it is often known as "castor oil plant" or "hedge castor oil plant",[3] but it is not the same as the usual castor oil plant, Ricinus communis (they are in the same family but different subfamilies). J. curcas is a semi-evergreen shrub or small tree, reaching a height of 6 m (20 ft) or more.[2] It is resistant to a high degree of aridity, allowing it to grow in deserts.[5][6] It contains phorbol esters, which are considered toxic.[7] However, edible (non-toxic) provenances native to Mexico also exist, known by the local population as piñón manso, xuta, chuta, aishte, among others.[8][9] J. curcas also contains compounds such as trypsin inhibitors, phytate, saponins and a type of lectin[10][11] known as curcin.[12] The seeds contain 27–40% oil[13] (average: 34.4%[14]) that can be processed to produce a high-quality biodiesel fuel, usable in a standard diesel engine. Edible (non-toxic) varieties can be used for animal feed and food. <h2 style="color: #000000; font-size: 1.5em;">Botanical features</h2> <ul> <li>Leaves: The leaves have significant variability in their morphology. In general, the leaves are green to pale green, alternate to subopposite, and three- to five-lobed with a spiral phyllotaxis.[16]</li> <li>Flowers: male and female flowers are produced on the same inflorescence, averaging 20 male flowers to each female flower,[17] or 10 male flowers to each female flower.[18] The inflorescence can be formed in the leaf axil. Plants occasionally present hermaphroditic flowers.[16]</li> <li>Fruits : fruits are produced in winter, or there may be several crops during the year if soil moisture is good and temperatures are sufficiently high. Most fruit production is concentrated from midsummer to late fall with variations in production peaks where some plants have two or three harvests and some produce continuously through the season.[16]</li> <li>Seeds: the seeds are mature when the capsule changes from green to yellow. The seeds contain around 20% saturated fatty acids and 80% unsaturated fatty acids, and they yield 25–40% oil by weight. In addition, the seeds contain other chemical compounds, such as saccharose, raffinose, stachyose, glucose, fructose, galactose, and protein. The oil is largely made up of oleic and linoleic acids. Furthermore, the plant also contains curcasin, arachidic, myristic, palmitic, and stearic acids and curcin.[16]</li> <li>Genome: the whole genome was sequenced by Kazusa DNA Research Institute, Chiba Japan in October 2010.</li> </ul> <h2 style="color: #000000; font-size: 1.5em;">Cultivation</h2> Cultivation is uncomplicated. Jatropha curcas grows in tropical and subtropical regions.[20] The plant can grow in wastelands and grows on almost any terrain, even on gravelly, sandy and saline soils. It can thrive in poor and stony soils, although new research suggests that the plant's ability to adapt to these poor soils is not as extensive as had been previously stated. Complete germination is achieved within 9 days. Adding manure during the germination has negative effects during that phase, but is favorable if applied after germination is achieved. It can be propagated by cuttings, which yields faster results than multiplication by seeds. The flowers only develop terminally (at the end of a stem), so a good ramification (plants presenting many branches) produces the greatest amount of fruits. The plants are self-compatible.[17] Another productivity factor is the ratio between female and male flowers within an inflorescence, more female flowers mean more fruits.[18] Jatropha curcas thrives on a mere 250 mm (10 in) of rain a year, and only during its first two years does it need to be watered in the closing days of the dry season. Ploughing and planting are not needed regularly, as this shrub has a life expectancy of approximately forty years. The use of pesticides is not necessary, due to the pesticidal and fungicidal properties of the plant. It is used in rural Bengal for dhobi itch (a common fungal infection of the skin). While Jatropha curcas starts yielding from 9–12 months time, the best yields are obtained only after 2–3 years time. The seed production is around 3.5 tons per hectare (seed production ranges from about 0.4 t/ha in the first year to over 5 t/ha after 3 years). If planted in hedges, the reported productivity of Jatropha is from 0.8 to 1.0 kg of seed per meter of live fence.[citation needed] <h2 style="color: #000000; font-size: 1.5em;">Propagation</h2> Jatropha curcas can easily be propagated by both seed or cuttings. Some people recommend propagation by seed for establishment of long-lived plantations.[22] When jatropha plants develop from cuttings, they produce many branches but yield fewer seeds and do not have enough time to develop their taproot, which makes them sensitive to wind erosion.[23] The seeds exhibit orthodox storage behaviour and under normal treatment and storage will maintain viability at high percentages for eight months to a year.[24][25][26][22][27] Propagation through seed (sexual propagation) leads to a lot of genetic variability in terms of growth, biomass, seed yield and oil content. Clonal techniques can help in overcoming these problems. Vegetative propagation has been achieved by stem cuttings, grafting, budding as well as by air layering techniques. Cuttings should be taken preferably from juvenile plants and treated with 200 micro gram per litre of IBA (rooting hormone) to ensure the highest level of rooting in stem cuttings.[28] Cuttings strike root easily stuck in the ground without use of hormones. <h2 style="color: #000000; font-size: 1.5em;">Processing</h2> Seed extraction and processing generally needs specialized facilities. Oil content varies from 28% to 30% and 80% extraction, one hectare of plantation will give 400 to 600 litres of oil if the soil is average.[29] The oily seeds are processed into oil, which may be used directly ("Straight Vegetable Oil") to fuel combustion engines or may be subjected to transesterification to produce biodiesel.[citation needed] Jatropha oil is not suitable for human consumption, as it induces strong vomiting and diarrhea.[citation needed] <h2 style="color: #000000; font-size: 1.5em;">Biofuel</h2> <div class="thumb tright" style="color: #202122; font-size: 14px;"> <div class="thumbinner" style="font-size: 13.16px;"><img alt="" src="https://upload.wikimedia.org/wikipedia/commons/thumb/1/13/Jatropha_in_Paraguay_Chaco.jpg/220px-Jatropha_in_Paraguay_Chaco.jpg" decoding="async" width="220" height="322" class="thumbimage" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/1/13/Jatropha_in_Paraguay_Chaco.jpg/330px-Jatropha_in_Paraguay_Chaco.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/1/13/Jatropha_in_Paraguay_Chaco.jpg/440px-Jatropha_in_Paraguay_Chaco.jpg 2x" data-file-width="684" data-file-height="1000"> <div class="thumbcaption" style="font-size: 12.3704px;"> <div class="magnify"></div> Jatropha plantation in the dry center/west of the Paraguay Chaco</div> </div> </div> When jatropha seeds are crushed, the resulting jatropha oil can be processed to produce a high-quality biofuel or biodiesel that can be used in a standard diesel car or further processed into jet fuel, while the residue (press cake) can also be used as biomass feedstock to power electricity plants, used as fertilizer (it contains nitrogen, phosphorus and potassium).

Treat your jatropha plant as well as possible to make the yield as large as possible!" (A reference to the compulsory planting of jatropha in Indonesia for the production of oil as machinery lubricant and fuel for the Japanese WWII war effort.)</div> </div> </div> There are several forms of biofuel, often manufactured using sedimentation, centrifugation, and filtration. The fats and oils are turned into esters while separating the glycerin. At the end of the process, the glycerin settles and the biofuel floats. The process through which the glycerin is separated from the biodiesel is known as transesterification. Glycerin is another by-product from Jatropha oil processing that can add value to the crop. Transesterification is a simple chemical reaction that neutralizes the free fatty acids present in any fatty substances in Jatropha. A chemical exchange takes place between the alkoxy groups of an ester compound by an alcohol. Usually, methanol and ethanol are used for the purpose. The reaction occurs by the presence of a catalyst, usually sodium hydroxide (NaOH) or caustic soda and potassium hydroxide (KOH), which forms fatty esters (e.g., methyl or ethyl esters), commonly known as biodiesel. It takes approximately 10% of methyl alcohol by weight of the fatty substance to start the transesterification process.[16] Estimates of Jatropha seed yield vary widely, due to a lack of research data, the genetic diversity of the crop, the range of environments in which it is grown, and Jatropha's perennial life cycle. Seed yields under cultivation can range from 1,500 to 2,000 kilograms per hectare, corresponding to extractable oil yields of 540 to 680 litres per hectare (58 to 73 gallons per acre).[31] In 2009 Time magazine cited the potential for as much as 1,600 gallons of diesel fuel per acre per year.[32] The plant may yield more than four times as much fuel per hectare as soybean, and more than ten times that of maize (corn), but at the same time it requires five times as much water per unit of energy produced as does corn (see below). A hectare of jatropha has been claimed to produce 1,892 litres of fuel.[33] However, as it has not yet been domesticated or improved by plant breeders, yields are variable.[34] Jatropha can also be intercropped with other cash crops such as coffee, sugar, fruits and vegetables.[35] In 2007 Goldman Sachs cited Jatropha curcas as one of the best candidates for future biodiesel production.[36] However, despite its abundance and use as an oil and reclamation plant, none of the Jatropha species has been properly domesticated and, as a result, its productivity is variable, and the long-term impact of its large-scale use on soil quality and the environment is unknown.[37] In 2008 researchers at Daimler Chrysler Research explored the use of jatropha oil for automotive use, concluding that although jatropha oil as fuel "has not yet reached optimal quality, ... it already fulfills the EU norm for biodiesel quality". Archer Daniels Midland Company, Bayer CropScience and Daimler AG have a joint project to develop jatropha as a biofuel.[38] Three Mercedes cars powered by Jatropha diesel have already put some 30,000 kilometres behind them. The project is supported by DaimlerChrysler and by the German Association for Investment and Development (Deutschen Investitions- und Entwicklungsgesellschaft, DEG). <h3 style="color: #000000; font-size: 1.2em;">Jet fuel</h3> Aviation fuels may be more widely replaced by biofuels such as jatropha oil than fuels for other forms of transportation. There are fewer planes than cars or trucks and far fewer jet fueling stations to convert than gas stations.[39] To fulfil the yearly demand for aviation fuel, based on demand in 2008 (fuel use has since grown), an area of farmland twice the size of France would need to be planted with jatropha, based on average yields of mature plantations on reasonably good, irrigated land.[40] On December 30, 2008, Air New Zealand flew the first successful test flight from Auckland with a Boeing 747 running one of its four Rolls-Royce engines on a 50:50 blend of jatropha oil and jet A-1 fuel.[39][41] In the same press release, Air New Zealand announced plans to use the new fuel for 10% of its needs by 2013. At the time of this test, jatropha oil was much cheaper than crude oil, costing an estimated $43 a barrel or about one-third of the June 4, 2008 closing price of $122.30 for a barrel of crude oil.[42] On January 7, 2009 Continental Airlines successfully completed a test flight from Houston, Texas using a 50/50 mixture of algae/jatropha-oil-derived biofuel and Jet A in one of the two CFM56 engines of a Boeing 737-800 Next Generation jet. The two-hour test flight could mark another promising step for the airline industry to find cheaper and more environmentally friendly alternatives to fossil fuel. On April 1, 2011 Interjet completed the first Mexican aviation biofuels test flight on an Airbus A320. The fuel was a 70:30 traditional jet fuel biojet blend produced from Jatropha oil provided by three Mexican producers, Global Energías Renovables (a wholly owned subsidiary of U.S.-based Global Clean Energy Holdings), Bencafser S.A. and Energy JH S.A. Honeywell's UOP processed the oil into Bio-SPK (Synthetic Paraffinic Kerosene).[43] Global Energías Renovables operates the largest Jatropha farm in the Americas.[43] On October 28, 2011 Air China completed the first successful demonstration flight by a Chinese airline that used jatropha-based biofuel. The mixture was a 50:50 mix of conventional jet fuel blended with jatropha oil from China National Petroleum Corp. The 747-400 powered one of its four engines on the fuel mixture during the 1-hour flight around Beijing airport.[44] On August 27, 2018 SpiceJet completed the first successful test flight by an Indian airline which used jatropha based biofuel. The ratio of conventional jet fuel to jatropha oil was 25:75.[45] <h3 style="color: #000000; font-size: 1.2em;">Carbon dioxide sequestration</h3> According to a 2013 study published by the European Geosciences Union,[46] the jatropha tree may have applications in the absorption of carbon dioxide, whose sequestration is important in combating climate change.[47] This small tree is very resistant to aridity so it can be planted in hot and dry land in soil unsuitable for food production. The plant does need water to grow though, so coastal areas where desalinated seawater can be made available are ideal. <h3 style="color: #000000; font-size: 1.2em;">Use in developing world</h3> Currently the oil from Jatropha curcas seeds is used for making biodiesel fuel in Philippines, Pakistan and in Brazil, where it grows naturally and in plantations in the southeast, north, and northeast of Brazil. In the Gran Chaco of Paraguay, where a native variety (Jatropha matacensis) also grows, studies have shown the suitability of Jatropha cultivation[48][49] and agro producers are starting to consider planting in the region.[50] In Africa, cultivation of jatropha is being promoted and it is grown successfully in countries such as Mali.[51] <h4 style="color: #000000; font-size: 14px;">India</h4> <div role="note" class="hatnote navigation-not-searchable" style="color: #202122; font-size: 14px;">Further information: Jatropha biodiesel in India</div> Jatropha oil is being promoted as an easily grown biofuel crop in hundreds of projects throughout India.[52] Large plantings and nurseries have been undertaken in India by many research institutions, and by women's self-help groups who use a system of microcredit to ease poverty among semiliterate Indian women. The railway line between Mumbai and Delhi is planted with jatropha and the train itself runs on 15–20% biodiesel.[34] <h4 style="color: #000000; font-size: 14px;">Myanmar[edit]</h4> <table class="box-Unreferenced_section plainlinks metadata ambox ambox-content ambox-Unreferenced" role="presentation" style="color: #202122; font-size: 14px;"> <tbody> <tr> <td class="mbox-image"> <div><img alt="" src="https://upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png" decoding="async" width="50" height="39" srcset="//upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/75px-Question_book-new.svg.png 1.5x, //upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/100px-Question_book-new.svg.png 2x" data-file-width="512" data-file-height="399"></div> </td> <td class="mbox-text"> <div class="mbox-text-span">This section does not cite any sources. Please help improve this section by adding citations to reliable sources.

On 15 December 2005, then-head of state, Senior General Than Shwe, said “the States and Divisions concerned are to put 50,000 acres (200 km²) under the physic nut plants [Jatropha] each within three years totalling 700,000 acres (2,800 km²) during the period”. On the occasion of Burma’s Peasant Day 2006, Than Shwe described in his a message that “For energy sector which is an essential role in transforming industrial agriculture system, the Government is encouraging for cultivation of physic nut plants nationwide and the technical know how that can refine physic nuts to biodiesel has also identified.” He would like to urge peasants to cultivate physic nut plants on a commercial scale with major aims for emergence of industrial agriculture system, for fulfilling rural electricity supply and energy needs, for supporting rural areas development and import substitute economy. (2005 from MRTV) In 2006, the chief research officer at state-run Myanma Oil and Gas Enterprise said Burma hoped to completely replace the country's oil imports of 40,000 barrels a day with home-brewed, jatropha-derived biofuel. Other government officials declared Burma would soon start exporting jatropha oil. Despite the military's efforts, the jatropha campaign apparently has largely flopped in its goal of making Burma self-sufficient in fuel. (2006 from MyawaddyTV) Z.G.S. Bioenergy has started Jatropha Plantation Projects in Northern Shan State, the company has begun planting Jatropha plants during late June 2007 and will start producing seeds by 2010. (20 July 2007 from New Light of Myanmar) <h3 style="color: #000000; font-size: 1.2em;">Controversies</h3> As of 2011 scepticism about the "miracle" properties of Jatropha has been voiced. For example: "The idea that jatropha can be grown on marginal land is a red herring", according to Harry Stourton, former business development director of UK-based Sun Biofuels, which attempted to cultivate Jatropha in Mozambique and Tanzania. "It does grow on marginal land, but if you use marginal land you'll get marginal yields," he said.[53][54] Sun Biofuels, after failing to adequately compensate local farmers for the land acquired for their plantation in Tanzania, pay workers severance, or deliver promised supplies to local villagers, went bankrupt later in 2011, the villager farmland being sold to an offshore investment fund.[55] An August 2010 article warned about the actual utility and potential dangers of reliance on Jatropha in Kenya. Major concerns included its invasiveness, which could disrupt local biodiversity, as well as damage to water catchment areas.[56] Jatropha curcas is lauded as being sustainable, and that its production would not compete with food production, but the jatropha plant needs water like every other crop to grow. This could create competition for water between the jatropha and other edible food crops. In fact, jatropha requires five times more water per unit of energy than sugarcane and corn.[57][58] <h2 style="color: #000000; font-size: 1.5em;">Food for human consumption</h2> Xuta, chuta, aishte or piñón manso (among others) are some of the names given in Mexico to edible non-toxic Jatropha curcas.[59][9] It is grown in house gardens or other small areas.[59] Although it is known as a toxic plant due to the presence of diterpenes named phorbol esters,[60] the existence of edible non-toxic J. curcas without phorbol esters content has been demonstrated.[9][61] It is also similarly reported that Jatropha seeds are edible once the embryo has been removed.[62] The process for analysis of phorbol ester contents in J. curcas is done through high-performance liquid chromatography (HPLC).[63] Xuta is traditionally prepared for local celebrations or popular parties. The kernels are roasted and eaten as a snack or roasted and ground to prepare different dishes, such as tamales, soups and sauces like “pipian”.[9][61] The seeds in the zone around Misantla, Veracruz are very appreciated by the population as food once they have been boiled and roasted. Root ashes are used as a salt substitute. HCN and rotenone are present.[64] <h2 style="color: #000000; font-size: 1.5em;">Other uses</h2> <ul style="color: #202122; font-size: 14px;"> <li>Flowers</li> </ul> <dl style="color: #202122; font-size: 14px;"> <dd>The species is listed as a honey plant. Hydrogen cyanide is present.[65]</dd> </dl> <ul style="color: #202122; font-size: 14px;"> <li>Nuts</li> </ul> <dl style="color: #202122; font-size: 14px;"> <dd>Can be construed for home cooking fuel in briquette form replacing charcoalized timber as in Haiti.[66]</dd> <dd>They can be burned like candlenuts when strung on grass.[citation needed] HCN is present.</dd> <dd>Used as a contraceptive in South Sudan.[68]</dd> </dl> <ul style="color: #202122; font-size: 14px;"> <li>Seeds</li> </ul> <dl style="color: #202122; font-size: 14px;"> <dd>Interest exists in producing animal feed[citation needed] from the bio-waste once the oil is expressed, as in the case with Haiti, where Jatropha curcas grows prolifically and animal feed is in very short supply.[66]</dd> <dd>Similarly, Metsiyen in the Haitian culture dates back as a medicinal crop—thus the name "metsiyen"/"medsiyen".

<h2>Bugás csörgőfa magok (Koelreuteria paniculata)</h2> <h2>A csomag ára 10 magot tartalmaz.</h2> A bugás csörgőfa vagy egyszerűen csörgőfa (Koelreuteria paniculata) a szappanfavirágúak (Sapindales) rendjébe, a szappanfafélék (Sapindaceae) családjába tartozó fás szárú, lombhullató növényfaj. Kelet-Ázsiában, Kína és Korea területén őshonos, Európába a 16. században török közvetítéssel került, díszfaként termesztik. Japán tengerpartjain és Dél-Európában betelepült fajként vadon is él. Az USA keleti részén, főként Floridában inváziós fajnak tekintik. Két változata ismert: <ul style="color: #202122; font-size: 14px;"> <li>Koelreuteria paniculata var. paniculata. Észak-Kínában és Koreában terjedt el. A levelek egyszeresen szeldeltek.</li> <li>Koelreuteria paniculata var. apiculata (Rehder & E.H.Wilson) Rehder (syn. K. apiculata). Nyugat-Kínában (Szecsuan) terjedt el, lépcsőzetesen átmenve a közép-kínai var. paniculata változattal. A nagyobb levélkéjű levelek gyakran kétszeresen szeldeltek.</li> </ul> <h2 style="color: #000000; font-size: 1.5em;">Jellemzői</h2> 5-10 méter magas, kerek koronájú fa. Kérge repedezett, világosbarna. Fiatal hajtásai vastagok, narancsos barnák. Levelei szárnyasan összetettek, 20–40 cm hosszúak, 11-13 erősen fűrészes szélű, csúcsos levélkéből állnak. A nagyobb levélkék a levél középpontján maguk is szeldeltek, de nem minden levél kétszer szeldelt, mint a Koelreuteria bipinnata fajnál. A levéllemez fényes zöld színű, fonákján kékes árnyalatú. Ősszel a levelek aranyos sárga, majd barna színt kapnak. A nyár második felében virágzik, az apró, illatos sárga, négy szirmú virágok látványos végálló bugavirágzatot alkotnak. Hímnős virágait méhek porozzák. Három élű toktermése 3–6 cm hosszú, 2–4 cm széles, felfújt hólyagra emlékeztet. Színe éretlenül zöld, éretten narancssárgás, ősszel sötétbarna.

It was greatly affected by the introduction of non-native plants such as the Chinese Fan-Palm, which created competition for space that it usually lost. Description Sabal bermudana grows up to 25 m (82 ft) in height, with the occasional old tree growing up to 30 m (98 ft) in height, with a trunk up to 55 cm (22 in) in diameter. It is a fan palm (Arecaceae tribe Corypheae), with the leaves with a bare petiole terminating in a rounded fan of numerous leaflets. Each leaf is 1.5–2 m (4.9–6.6 ft) long, with 45-60 leaflets up to 75 cm (30 in) long. The flowers are yellowish-white, 5 mm (0.20 in) across, produced in large panicles up to 2.5 m (8.2 ft) long, extending out beyond the leaves. The fruit is a deep brown to black drupe about 1 cm (0.39 in) long containing a single seed. It is extremely salt-tolerant and is often seen growing near the Atlantic Ocean coast in Bermuda, and also frost-tolerant, surviving short periods of temperatures as low as -14 °C, although it will never get that cold in Bermuda. Uses Bermudians used to use, for a short period, the leaflets of the palm to weave into hats and export them to the United Kingdom and other countries. Sabal bermudana also had hole drilled into its trunk and sap extracted to make "bibby", a strong alcoholic beverage. During the 17th century, most houses in Bermuda had palmetto-thatched roofs. </div>

<h2>Seeds Sago Palm, King Sago, Sago Cycad, Japanese Sago Palm</h2> <h2>Price for Package of 3 seeds.</h2> Cycas revoluta (Sotetsu [Japanese ソテツ], sago palm, king sago, sago cycad, Japanese sago palm), is a species of gymnosperm in the family Cycadaceae, native to southern Japan including the Ryukyu Islands. It is one of several species used for the production of sago, as well as an ornamental plant. Names Cycads are not closely related to the true palms (Arecaceae). The Latin specific epithet revoluta means "curled back",[2] in reference to the leaves. This is also called Kungi (comb) Palm in Urdu speaking areas. Description This very symmetrical plant supports a crown of shiny, dark green leaves on a thick shaggy trunk that is typically about 20 cm (7.9 in) in diameter, sometimes wider. The trunk is very low to subterranean in young plants, but lengthens above ground with age. It can grow into very old specimens with 6–7 m (over 20 feet) of trunk; however, the plant is very slow-growing and requires about 50–100 years to achieve this height. Trunks can branch multiple times, thus producing multiple heads of leaves. The leaves are a deep semiglossy green and about 50–150 cm (20–59 in) long when the plants are of a reproductive age. They grow out into a feather-like rosette to 1 m (3.3 ft) in diameter. The crowded, stiff, narrow leaflets are 8–18 cm (3.1–7.1 in) long and have strongly recurved or revolute edges. The basal leaflets become more like spines. The petiole or stems of the sago cycad are 6–10 cm (2.4–3.9 in) long and have small protective barbs. Roots are called coralloid with an Anabaena symbiosis allowing nitrogen fixation. Tannins-rich cells are found on either side of the algal layer to resist the algal invasion. As with other cycads, it is dioecious, with the males bearing pollen cones (strobilus) and the females bearing groups of megasporophylls. Pollination can be done naturally by insects or artificially. Cultivation and use Propagation of Cycas revoluta is either by seed or by removal of basal offsets. It is one of the most widely cultivated cycads, grown outdoors in warm temperate and subtropical regions, or under glass in colder areas. It grows best in sandy, well-drained soil, preferably with some organic matter. It needs good drainage or it will rot. It is fairly drought-tolerant and grows well in full sun or outdoor shade, but needs bright light when grown indoors. The leaves can bleach somewhat if moved from indoors to full sun outdoors. Of all the cycads, C. revoluta is the most popular in cultivation. It is seen in almost all botanical gardens, in both temperate and tropical locations. In many areas of the world, it is heavily promoted commercially as a landscape plant. It is also quite popular as a bonsai plant. First described in the late 18th century, it is tolerant of mild to somewhat cold temperatures, provided the ground is dry. Frost damage can occur at temperatures below −10 °C (14 °F), and several healthy plants have been grown with little protection as far north as St. Louis Missouri and New York, New York, both in USDA zone 7b. C. revoluta usually defoliates in this temperate climate, but will usually flush (or grow) several new leaves by spring. This plant has gained the Royal Horticultural Society's Award of Garden Merit. The pith contains edible starch, and is used for making sago. Before use, the starch must be carefully washed to leach out toxins contained in the pith. Extracting edible starch from the sago cycad requires special care due to the poisonous nature of cycads. Cycad sago is used for many of the same purposes as palm sago. Sago is extracted from the sago cycad by cutting the pith from the stem, root and seeds of the cycads, grinding the pith to a coarse flour and then washing it carefully and repeatedly to leach out the natural toxins. The starchy residue is then dried and cooked, producing a starch similar to palm sago/sabudana. The cycad seed contains cycasin toxin and should not be eaten as it is possible for cycasin toxin to survive the most vigorous of repeated washings. Cycasin toxin can cause ALS, Parkinson's, prostate cancer and fibrolemellar hepatocellular carcinoma. Aulacaspis yasumatsui is a scale insect feeding on C. revoluta, and unchecked is able to destroy the plant. Chemistry The hydro-alcoholic extract of leaves of C. revoluta shows the presence of alkaloids, steroids and tannins while the chloroform extract shows the presence of saponins, tannins and sugars.[8] Leaflets also contain biflavonoids.[9] Estragole is the primary volatile compound emitted from the male and female cones of C. revoluta. Toxicity Cycad sago is extremely poisonous to animals (including humans) if ingested. Pets are at particular risk, since they seem to find the plant very palatable.[11] Clinical symptoms of ingestion will develop within 12 hours, and may include vomiting, diarrhea, weakness, seizures, and liver failure or hepatotoxicity characterized by icterus, cirrhosis, and ascites. The pet may appear bruised, have nose bleeds (epistaxis), melena (blood in the stool), hematochezia (bloody straining), and hemarthrosis (blood in the joints).[12] The ASPCA Animal Poison Control Center estimates a fatality rate of 50 to 75% when ingestion of the sago palm is involved. If any quantity of the plant is ingested, a poison control center or doctor should be contacted immediately. Effects of ingestion can include permanent internal damage and death. All parts of the plant are toxic; however, the seeds contain the highest level of the toxin cycasin. Cycasin causes gastrointestinal irritation, and in high enough doses, leads to liver failure.[13] Other toxins include Beta-methylamino L-alanine, a neurotoxic amino acid, and an unidentified toxin which has been observed to cause hindlimb paralysis in cattle. <script src="//cdn.public.n1ed.com/G3OMDFLT/widgets.js"></script>

<h2>European fan palm, Mediterranean dwarf palm Seeds (Chamaerops humilis)</h2> <h2>Price for Package of 3 seeds.</h2> Chamaerops is a genus of flowering plants in the palm family Arecaceae. The only currently fully accepted species is Chamaerops humilis, variously called European fan palm, or the Mediterranean dwarf palm. It is one of the more cold-hardy palms used in landscaping in temperate climates. Chamaerops humilis is a shrub-like clumping palm, with several stems growing from a single base. It has an underground rhizome which produces shoots with palmate, sclerophyllous leaves. The stems grow slowly and often tightly together, eventually reaching 2–5 m (10–20 ft) tall with a trunk diameter of 20–25 cm (8–10 in). It is a fan palm (Arecaceae tribe Corypheae), and as such, has leaves with petioles terminating in rounded fans of 10–20 leaflets. Each leaf is up to 1.5 m (5 ft) long, with leaflets 50–80 cm (20–30 in) long. The petioles are armed with numerous sharp, needle-like spines; these may protect the stem growing point from browsing animals. The flowers are borne in dense, short inflorescences at the tops of the stems. The plants usually, but not invariably, are dioecious with male and female flowers on separate plants. The prophyll covers the flowers on the inflorescence until the sexual phase (anthesis) and then splits open apically into two triangular lobes. The number of flowers per inflorescence is highly variable for both male and female plants, depending on the size of the inflorescence. Female flowers are tri-ovulate.[6] Unripe fruits are bright green, turning to dull yellow to brown as they ripen during autumn (September–November). The seed (usually 0.6–0.8 g or 1⁄50–3⁄100 oz) contains a small cylindrical embryo, which is surrounded by several layers, from inner to outer as follows: a nutritious endosperm, a wide woody layer or endocarp, a fleshy and fibrous mesocarp (the pulp), and the thin outer layer or exocarp. Taxonomy Apart from the fully accepted Chamaerops humilis there currently are a few species of unresolved status plus tens of species synonymised with Chamaerops humilis. The species Chamaerops humilis itself has three accepted varieties as follows: Chamaerops humilis var. argentea André (syn. C. h. var. cerifera) – "Atlas mountain palm" of Northwest Africa. Leaves glaucous. Chamaerops humilis var. epondraes – Northwest Africa. Leaves glaucous. Chamaerops humilis var. humilis – Southwest Europe. Leaves green. There also are at least three cultivars (C. humilis var. humilis 'Nana', C. humilis 'Vulcano', C. humilis 'Stella'). C. humilis 'Vulcano' is a compact, thornless cultivar. May be silvery, but less so than argentea. The leaves tend to be thicker, and the appearance of the plant is bushier than var. humilis or var. argentea. The genus Chamaerops is closely related to the genus Trachycarpus. The genera differ in that Trachycarpus lacks the clumping habit only forms single stems without basal suckers), the spiny leaf stems (spineless in Trachycarpus), and in small details of the flower anatomy. Distribution Chamaerops humilis is one of only two palm species native to southern Europe, the other being Phoenix theophrasti. It is mainly found in southwestern Europe (Malta, Sicily, over all the Mediterranean coast of Spain and Portugal, central and southern Italy, some parts of the southern Mediterranean coast of France and Monaco, as well as northwest Africa (Morocco, Algeria, Tunisia). It is the northernmost naturally occurring palm in the world, with the northernmost standing at Hyères-les-Palmiers, at 43° 07′ N. Cultivation Chamaerops humilis is valued in gardening and landscaping in many parts of the world. It is very drought-tolerant once established. It is hardy to −12 °C (10 °F), but does prefer hot summers. It is a very slow-growing plant. The blue form of the species, native to high elevations of the Atlas Mountains, has recently been introduced into the trade and early reports indicate that it may be −12 °C (−22 °F) or more degrees hardier than the green form. It has gained the Royal Horticultural Society's Award of Garden Merit. Ecology and interactions with animals Chamaerops humilis flowers in spring, typically from April to May. The plant also may be partly anemophilous, that is to say, wind-pollinated, but it is at least partly entomophilous, that is to say dependent on pollination by insects. Only one insect species is known to pollinate it, namely a specific weevil, Derelomus chamaeropsis in the family Curculionidae.[13] The nature of the relationship with the weevil is a version of nursery pollination mutualism with the weevil; the form this takes is that once pollinating weevils have found a satisfactory plant, whether male or female, they usually stay on the same plant until the end of its anthesis, finding shelter, egg-laying sites, and food in the inflorescences. At anthesis, as is common in Angiosperms, both male and female Chamaerops humilis plants attract their pollinators with chemical compounds, but an unusual feature is that their scents are released by the leaves, and not by the flowers.[15] Towards the end of anthesis, weevils leave the plant and seek a new host plant, again either male or female. Larval development of the weevil Derelomus chamaeropsis occurs within rachises of inflorescences of male plants during autumn and winter. At the beginning of the next flowering period, adult weevils emerge from the dry and brittle stems of old inflorescences of the previous year of male plants only. Those that hatch in female plants die without concluding their development. This is because the palmettos are adapted to prevent the pollinating weevils from destroying the female inflorescences with their burden of seed. Weevils have been shown to lay eggs within female inflorescences, but as soon as seeds start to develop, eggs or larvae fail to continue their life cycle. On the other hand, male inflorescences have completed their function after pollination, so it is advantageous to the plant's reproduction for the weevils to complete their life cycles and shelter in the male inflorescences, thereby remaining available for pollination when they emerge in the following season. The ripe pulp of C. humilis has several important functions. When ripened, the pulp smells strongly of rancid butter[18] and thus acts as a foraging cue for nocturnal frugivores that commonly are fundamentally carnivorous mammals such as badgers and foxes. The pulp inhibits germination, ensuring that the seed does not germinate until has been dispersed. The pulp also acts as a chemical or physical barrier against invertebrate seed predators, typically beetles, and in particular weevils. Because of the combination of such functions in the pulp, the palm both benefits and suffers adverse consequences when carnivores feed on the fruit and thereby remove the pulp. On the one hand, the seeds that carnivores swallow, germinate more frequently than seeds in entire fruit. On the other hand, ingested seeds are more frequently destroyed by invertebrate pests than non-ingested seeds. However, because of the mobility of carnivores, their dispersal service is important to the palmetto, given the severe fragmentation and isolation of most populations across the increasingly densely populated Mediterranean basin. Uses and threats Chamaerops humilis has a wide distribution in uncultivated land, and it is adapted to regimes of frequent burning, which it survives largely by re-sprouting from underground rhizomes and from fire-damaged stems. Such factors make the species ecologically important in preventing erosion and desertification and in providing shelter and food to many species of animals. Apart from its material benefits, this palmetto is of emotional value as a charismatic component of the "garrigues" and "macchias" of the Mediterranean coastline. The leaves of the adult plants have been used to make brooms and for weaving mats, carrier baskets, and similar articles. For finer work the young, unopened leaves are treated with sulphur to soften them softer and provide supple fibre. The husk, known in southern Spain as "higa", is edible before it becomes too tough to eat as it matures. Because of their bitterness and high tannin content, the fruit are not used for human food, but in traditional medicine they have been used as an astringent.[19] Urbanization and other human activities are making such rapid inroads into the natural habitat of palmetto that they are raising concerns about its future and that of its environment. Accordingly there is an increase in regulations to protect both its stands and those of associated Mediterranean endemics. Another conservation problem is that particularly in the northernmost parts of its natural range, Chamaerops humilis is seriously threatened by an introduced South American moth Paysandisia archon.[9][20] Also, this Mediterranean native palm is affected by the introduction of related ornamental species because of the concurrent introduction of seed predators (such as Coccotrypes dactyliperda and Dactylotrypes longicollis) that feed on both the introduced and native palms.
