The coconut palm (Cocos nucifera) is a member of the family Arecaceae (palm family). It is the only species in the genus Cocos, and is a large palm, growing to 30 m tall, with pinnate leaves 4–6 m long, and pinnae 60–90 cm long; old leaves break away cleanly, leaving the trunk smooth. The term coconut refers to the seed of the coconut palm. The spelling cocoanut is an old-fashioned form of the word.[2] The coconut palm is grown throughout the tropics for decoration, as well as for its many culinary and non-culinary uses; virtually every part of the coconut palm has some human uses. In cooler climates (but not less than USDA Zone 9), a similar palm, the queen palm (Syagrus romanzoffiana) is used in landscaping. Its fruit are very similar to the coconut but much smaller. It was originally classified in Cocos genus along with the coconut, but was later moved to Syagrus. A recently discovered palm, Beccariophoenix alfredii from Madagascar is nearly identical to the coconut, more so than the queen palm. It is cold-hardy and makes a coconut-lookalike for cooler areas. The coconut has spread across much of the tropics, probably aided in many cases by seafaring people. Coconut fruit in the wild is light, buoyant and highly water resistant, and evolved to disperse significant distances via marine currents.[3] Fruit collected from the sea as far north as Norway are viable. In the Hawaiian Islands, the coconut is regarded as a Polynesian introduction, first brought to the islands by early Polynesian voyagers from their homelands in Oceania. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America. The flowers of the coconut palm are polygamomonoecious, with both male and female flowers in the same inflorescence. Flowering occurs continuously. Coconut palms are believed to be largely cross-pollinated, although some[which?] dwarf varieties are self-pollinating. The "nut" of the coconut is the edible endosperm, located on the inner surface of the shell. Inside the endosperm layer, coconuts contain an coconut juice that is sweet or salty or both sweet and salty. Coconuts received the name from Portuguese explorers, the sailors of Vasco da Gama in India, who first brought them to Europe. The brown and hairy surface of coconuts reminded them of a ghost or witch called Coco.[4] Before it was called nux indica, name given by Marco Polo in 1280 while in Sumatra, name taken from the Arabs who called it jauz-al-Hindi. When coconuts arrived in England, they retained the coco name and nut was added.
[edit] OriginsThe origins of this plant are the subject of debate.
[edit] Natural habitat A germinating coconut The coconut palm thrives on sandy soils and is highly tolerant of salinity. It prefers areas with abundant sunlight and regular rainfall (150 cm to 250 cm annually), which makes colonizing shorelines of the tropics relatively straightforward.[5] Coconuts also need high humidity (70–80%+) for optimum growth, which is why they are rarely seen in areas with low humidity, like the Mediterranean, even where temperatures are high enough (regularly above 24°C or 75.2°F). Coconut palms require warm conditions for successful growth, and are intolerant of cold weather. Optimum growth is with a mean annual temperature of 27 °C (81 °F), and growth is reduced below 21 °C (70 °F). Some seasonal variation is tolerated, with good growth where mean summer temperatures are between 28–37 °C (82–99 °F), and survival as long as winter temperatures are above 4–12 °C (39–54 °F); they will survive brief drops to 0 °C (32 °F). Severe frost is usually fatal, although they have been known to recover from temperatures of −4 °C (24.8 °F).[5] They may grow but not fruit properly in areas where there is not sufficient warmth, like Bermuda. The conditions required for coconut trees to grow without any care are:
The main limiting factor is that most locations which satisfy the first three requirements do not satisfy the fourth, except near the coast where the sandy soil and salt spray limit the growth of most other trees (Palmtalk[6]). The range of the natural habitat of the coconut palm tree is delineated by the red line in map C1 to the right (based on information in Werth 1933,[7] slightly modified by Niklas Jonsson). [edit] CultivationCoconut trees are very hard to establish in dry climates, and cannot grow there without frequent irrigation; in drought conditions, the new leaves do not open well, and older leaves may become desiccated; fruit also tends to be shed.[5] Coconut palms are grown in more than 80 countries of the world, with a total production of 49 billion nuts. The 2007 shares of coconut growing countries in production were: Indonesia (26%), Philippines (23%), India (23%), Sri Lanka (4.4%), other countries (24%). The productivity of the crop is the highest in India with 7572 nuts/ha.
[edit] HarvestingIn some parts of the world (Thailand and Malaysia), trained pig-tailed macaques are used to harvest coconuts. Training schools for pig-tailed macaques still exist both in southern Thailand, and in the Malaysian state of Kelantan.[8] Competitions are held each year to find the fastest harvester. [edit] Pests and diseasesMain article: List of coconut palm diseases Coconuts are susceptible to the phytoplasma disease lethal yellowing. One recently selected cultivar, 'Maypan', has been bred for resistance to this disease. The fruit may also be damaged by eriophyid coconut mites. The coconut is also used as a food plant by the larvae of many Lepidoptera (butterfly and moth) species, including Batrachedra spp: B. arenosella, B. atriloqua (feeds exclusively on Cocos nucifera), B. mathesoni (feeds exclusively on Cocos nucifera), and B. nuciferae. Brontispa longissima (the "coconut leaf beetle") feeds on young leaves and damages seedlings and mature coconut palms. On September 27, 2007, Philippines' Metro Manila and 26 provinces were quarantined due to having been infested with this pest (to save the $800-million Philippine coconut industry).[9] In Kerala the major pests of coconut are the Eriophyid mite, the rhinoceros beetle, the red Palm weevil and the coconut leaf caterpillar. The hyid coconut mite (Eriophyes guerreronis) is devastating, and can cause damages up to 90% in coconut production. The immature nuts are infested and desapped by larvae staying in the portion covered by the perianth of the immature nut. Subsequently, the nuts drop off or survive deformed. Spraying with wettable sulfur 0.4% alternately with neem-based pesticides can give some relief, but is cumbersome and labor intensive. Research on this topic gave no results and the researchers from the Kerala Agricultural University and the Central Plantation Crop Research Institute, Kasaragode are still searching for a cure. The /Krishi Vigyan Kendra, Kannur under Kerala Agricultural University has developed an innovative extension approach called Compact area group approach (CAGA) to combat coconut mites. [edit] IndiaTraditional areas of coconut cultivation in India are the states of Kerala, Tamil Nadu, Karnataka, Andhra Pradesh, Orissa, West Bengal, Pondicherry, Maharashtra and Islands of Lakshadweep and Andaman and Nicobar. Kerala is the largest coconut growing state in India, and is famous for the most tender coconuts in India. And, they are also famous for the coconut-based products like tender coconut water, copra, coconut oil, coconut cake, coconut toddy, coconut shell-based products, coconut wood-based products, coconut leaves, and coir pith. Four southern states put together account for 92% of the total production in the country (Kerala 45.22%, Tamil Nadu 26.56%, Karnataka 10.85%, Andhra Pradesh 8.93% and other states 8.44%). The above data are as per Kerala Agriculture Site. [10] Coconut is cultivated mainly in the following Indian States
[edit] US A coconut tree in Cuba The only states in the U.S. where coconut palms can be grown and reproduced outdoors without irrigation are Hawaii and south Florida. Coconut palms will grow from coastal Pinellas County and St. Petersburg southwards on Florida's west coast, and Melbourne southwards on Florida's east coast. The occasional coconut palm is seen north of these areas in favoured microclimates in the Tampa and Clearwater metro area and around Cape Canaveral, as well as the Orlando-Kissimmee-Daytona Beach metro area. They may likewise be grown in favored microclimates in the Rio Grande Valley area of Deep South Texas near Brownsville and on Galveston Island. They may reach fruiting maturity, but are damaged or killed by the occasional winter freezes in these areas. While coconut palms flourish in south Florida, unusually bitter cold snaps can kill or injure coconut palms there as well. Only the Florida Keys and the coastlines provide safe havens from the cold for growing coconut palms on the U.S. mainland. The farthest north in the United States a coconut palm has been known to grow outdoors is in Newport Beach, California along the Pacific Coast Highway. For coconut palms to survive in Southern California, they need sandy soil and minimal water in the winter to prevent root rot, and would benefit from root heating coils. [edit] Middle EastThe main coconut producing area in the Middle East is the Dhofar region of Oman. In particular, the area around Salalah maintains large coconut plantations similar to those found across the Arabian Sea. The large coconut groves of Dhofar were mentioned by the medieval Moroccan traveller Ibn Battuta in his writings, known as Al Rihla.[11] This is possible due to an annual rainy season known locally as Khareef. Coconuts also are increasingly grown for decorative purposes along the coasts of the UAE and Saudi Arabia with the help of irrigation. The UAE have, however, imposed strict laws on mature coconut tree imports from other countries to reduce the spread of pests to other native palm trees, such as the date palm.[12] [edit] Plant[edit] Nut
Botanically, a coconut is a simple dry nut. The husk, or mesocarp, is composed of fibers called coir; the inner stone, or endocarp is the hardest part of the nut. The endocarp (the outside of the coconut as sold in the shops of non-tropical countries) has three germination pores that are clearly visible on the outside surface once the husk is removed. It is through one of these that the radicle emerges when the embryo germinates. Adhering to the inside wall of the endocarp is the testa, with a thick albuminous endosperm (the coconut "meat"), the white and fleshy edible part of the seed. Although coconut meat contains less fat than other dry nuts, such as almonds, it is noted for its high amount of medium-chain saturated fat.[13] About 90% of the fat found in coconut meat is saturated, a proportion exceeding that of foods such as lard, butter, and tallow. However, there has been some debate as to whether or not the saturated fat in coconuts is healthier than the saturated fat found in other foods (see coconut oil for more information). Coconut meat also contains less sugar and more protein than popular fruits such as bananas, apples and oranges, and it is relatively high in minerals such as iron, phosphorus and zinc. The endosperm surrounds a hollow interior space, filled with air and often a liquid referred to as coconut water, not to be confused with coconut milk. Coconut milk, called "santan" in Malay and "katas ngungut" in Kapampangan, is made by grating the endosperm and mixing it with warm water. The resulting thick, white liquid is used in much Asian cooking, for example, in curries. Coconut water from the unripe coconut can be drunk fresh. Young coconuts used for coconut water are called tender coconuts. When the coconut is still green, the endosperm inside is thin and tender, and is often eaten as a snack. But the main reason to pick the fruit at this stage is to drink its water. The water of a tender coconut is liquid endosperm. It is sweet (mild) with an aerated feel when cut fresh. Depending on the size, a tender coconut could contain the liquid in the range of 300 to 1,000 ml. The meat in a young coconut is softer and more gelatinous than a mature coconut, so much so, that it is sometimes known as coconut jelly. When the coconut has ripened and the outer husk has turned brown, a few months later, it will fall from the palm of its own accord. At that time the endosperm has thickened and hardened, while the coconut water has become somewhat bitter. When the coconut fruit is still green, the husk is very hard, but green coconuts only fall if they have been attacked by molds, etc. By the time the coconut naturally falls, the husk has become brown, the coir has become drier and softer, and the coconut is less likely to cause damage when it drops. Still, there have been instances of coconuts falling from palms and injuring people, and claims of some fatalities. This was the subject of a paper published in 1984 that won the Ig Nobel Prize in 2001. Falling coconut deaths are often used as a comparison to shark attacks; the claim is often made that a person is more likely to be killed by a falling coconut than by a shark, yet, there is no evidence of people ever being killed in this manner.[14] When viewed on end, the endocarp and germination pores give the fruit the appearance of a coco (also Côca), a Portuguese word for a scary witch from Portuguese folklore, that used to be represented as a carved vegetable lantern, hence the name of the fruit.[15] The specific name nucifera is Latin for nut-bearing. A small number of writings about coconut mention the existence of the coconut pearl due to the rarity of the gem.[16] Reginald[16] mentions in his book a few publishings whose author purposely avoided discussion about the vegetable-gem. [edit] HuskIn Thailand, the coconut husk is used as a potting medium because of its cost-effectiveness to produce healthy forest tree saplings. The process of husk extraction from the coir bypasses the retting process, using a custom-built coconut husk extractor designed by ASEAN-Canada Forest Tree Seed Centre (ACFTSC) in 1986. Fresh husks contains more tannin than old husks. Tannin produces negative effects on sapling growth.[17] In India, the coconut husk is used extensively in the manufacture of coir, which is subsequently used in the production of rope, as well as household products like door mats and sacks.[citation needed] [edit] ShellIn India, coconut shells are used as bowls and in the manufacture of various crafts products. In certain parts of South India, the shell and husk also are burned for smoke to repel mosquitoes. Coconut shell is sometimes used to 'ward away the evil eye' in South India. The shell composition is shown in the tables below.
[edit] RootsUnlike some other plants, the palm tree has neither tap root nor root hairs; but has a fibrous root system.[18] [edit] InflorescenceOn the same inflorescence, the palm produces both the female and male flowers; thus the palm is monoecious.[18] Coconut Flower and Kerala Marriage
[edit] UsesNearly all parts of the coconut palm are useful. The palms have a comparatively high yield, up to 75 fruits per year[citation needed]; it therefore has significant economic value. The name for the coconut palm in Sanskrit is kalpa vriksha, which translates as "the tree which provides all the necessities of life". In the Malay language, the coconut is known as pokok seribu guna, "the tree of a thousand uses". In the Philippines, the coconut is commonly given the title "Tree of Life".[citation needed] [edit] Culinary
