Type I and II (22–24 day interval; emasculation 5 days after spathe opening; bagging 3 days later); Type III (0 interval; emasculation and bagging 48 hours before natural opening); and Type IV (emasculation the day of natural opening; bagging 3 days later). Rognon F. 1976. It is a type of racemose inflorescence. In a year a coconut tree generally produces 12–20 inflorescences. The following regeneration guidelines are based mainly on the manual prepared by Santos et al. A safety margin of 8 days between bagging the inflorescence and harvesting the pollen is sufficient to ensure the death of virtually all the pollen grains which were on the inflorescence when it was bagged. Coconut palms can be classified according to the size and stature of the palm, and are referred to as Talls and Dwarfs. (15.2-30.5 cm); brown, green, yellow, showy; does not attract wildlife Step 2. The wood of the coconut palm is known in the lumber trade as "porcupine wood". (photo: Fonana Youssouf), Hand pollinating a female coconut flower. Maintain seedbeds with daily watering and partial shading, and inspect for disease and pest incidence. Common name. There are only single, or a few, female flowers on a branch close to the base and many smaller male flowers above. 1980. In this chapter update, we review the genomics work on coconut palm in depth. Coconuts are conserved ex situ in field genebanks, but are propagated from seed. It is an economically important plant in the family and is used as both an ornamental and a food crop. The fruit of the coconut is a fibrous drupe. Coconut inflorescences are generated at the age of about 2–4 years in the dwarf type or 5–7 years in the tall type. 2008. The few which might still be viable at the time would not survive the preparation and conditioning of the pollen. Place the earliest germinating seedlings in the first row in the eastern side of the area and the later germinating seedlings on the western side to reduce competition for sunlight. Available here (4.4 MB). Coconut is an important subsistence crop of the humid tropical zones and is a life-supporting species in fragile island and coastal ecosystems. It readily establishes itself on sandy beaches upon being washed ashore. Sangare A, Rognon F, Nuce de Lamothe M de. Generally coconut is classified into dwarf and tall groups. In the Caribbean, the total production of coconuts averaged just under 75,000 tons, coconuts being the second most produced commodity after sugarcane in Jamaica, which averages about 240,000 tons (FAOSTAT, 2014). Pollen shedding overlaps with the opening of the female flowers. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, taking 15 to 20 years to reach peak production. Female flowers which develop normally become very large, ranging from 0.5 to more than 2.5 kg. One year is required between pollination and harvest and another year for the plant to grow in the nursery. Slice off the small part of the top of the husk to help retain moisture in the husk during watering and to encourage germination. They have been found in the Caribbean and the Atlantic coasts of Africa and South America for less than 500 years (the Caribbean native inhabitants do not have a dialect term for them, but use the Portuguese name), but evidence of their presence on the Pacific coast of South America antedates Christopher Columbus’s arrival in the Americas. Prepare the pollen–talc mixture and pollinate by hand when most of the flowers have their stigmata open and are secreting nectar (see photo). The trees are tall, reaching up to 30 m in height, with a slender, often curved trunk. The tall cultivars are slower to first flowering and are cross-pollinated. Before the palms reach a height which makes controlled pollinations difficult. Main ingredients are the tender coconut inflorescence( Narikela pushpa), Almonds, palm candy sugar, dry black raisins, dates, cardamom, saffron, milk to name a few. It can be polished and varnished to make containers. 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. These guidelines have been peer reviewed by V. Ramanatha Rao, India, and Gerardo A. Santos, Philippines. On Palm Sunday, Filipinos bring coconut fronds, called palaspas, to the Church, to commemorate Jesus’ triumphal entry into Jerusalem. The fruit can float and endure long journeys in seawater. Using a sharp knife, tap the inflorescence by slicing at least 6mm to cut the tissues and eventually allow the surge of the sap. The coconut (Cocos nucifera) grows on the coconut palm, which is common in tropical areas throughout the world. Cover the base of the crown with loose topsoil, slightly firmed at the base of the crown. Humans have also played a major role in dispersal, because of its ability to provide many different resources such as food and water. Avoid writing on the plastic bag. When the sprout emerges through the husk to a height of 4–6 cm, trim seedlings of any injured roots and plant in polybags filled with appropriate soil–manure mixture. Laguna Tall coconut fruits from the Philippines. Konan J-L, Bourdeix R, Batugal P. 2005. La fécondation artificielle du cocotier [The controlled pollination of coconut]. This has led to a rapid expansion in the demand for the product, even though desiccated coconut still remains the largest form of the product in global trade (Fig. It is ovoid in shape with three sides divided by ridges. About 4 months is needed for this controlled pollination process, including pollen harvest, bagging of the inflorescences, pollination and removing the bags. After planting in the field, mark the palm by painting the trunk to avoid any error during the observation. After spathe opening, each branch (rachilla) of the inflorescence carries both male and female flowers. The information on this page was extracted from: Pollinisation assistée et contamination par des pollens indésirables [Assisted pollination and contamination by undesirable pollen]. Apply mechanical, chemical or biological treatment depending on the pest on advice by your plant health expert. Density of palms depends on the type of accession. Production and provision of hybrid seednuts. Cut down thick vegetation, clear debris, then plough and harrow to improve soil tilth. Lay out the polybag nursery to enable equal setting of the seedlings at optimum distance, following a triangular system with equal spacing of 60cm (see photo). Apply fertilizer 2 months after germination (20g (NH. Dwarfs should be planted at a density of 205 palms/ha with a spacing of 6.5m between palms and 5.6 m between rows. In the case of autogamous (dwarf) varieties in which the male phase starts as soon as the spathe opens naturally, put the bag on 72 to 48 hours before the presumed date of opening. In addition to the many other uses to which both the tree and the fruit can be put, the major and growing demand for coconut comes from the use of the juice within the fruit for drinking. The coconut palm Cocos nucifera belongs to the palm family, one of the largest in the monocotyledon group. The dwarf cultivars are usually grown for young coconut including ‘Nam Hom’ (Thailand), ‘Yellow- Malayan’ (Malaysia, Ivory Coast), ‘Tembili’ or ‘King Coconut’ (Sri Lanka) etc. The bunch is ready for harvesting when at least one nut has a brown husk or if the water inside the nut cavity sloshes around when shaken. Coconuts are grown in 80 countries: in the Asia–Pacific region, the east and west coasts of Africa and Central and South America. It has generally been accepted that the coconut originated in the Indian–Indonesia region and float-distributed itself around the world by riding ocean currents. 10 pp. When the number of living palms is less than 75 for cross-pollinating varieties or less than 30 for self-pollinating varieties. A tall coconut with niu kafa fruit. Since the fruit is monospermous, it encloses a single seed. Regeneration guidelines: coconut. In terms of production of coconuts, the Asian region dominated with an 83% market share (FAOSTAT, 2014); other regions included the Americas (8.7%), Oceania (4.8%), and Africa (3.4%). Male parent 1 is used to pollinate female parents 1 and 2; male parent 2 is used to pollinate female 2 and 3; and so on, following the sequential double pair mating procedure. The palm is monoecious, i.e. The exocarp, or the epidermis, is about 0.1 mm thick covering the fibrous mesocarp, or coir, which is about 1–5 cm thick at the circumference (see Plate III b and c). 2005. Make a slight depression towards the base of the crown to trap rainwater. The information on this page was extracted from: Soil: wide range of soil types from sandy loam to heavy clay. The top of the nut must be about 5–8 cm below the ground level. The inflorescence is a cymose panicle, formed in the axil of the leaves on several stem segments (Figs 11.2 and 11.5). Never leave them in the plantation overnight in case of accidental mixing or loss. Carefully record pollinations and harvesting. The coconut palm is tall and stately in appearance and attains a height of about 15–30 m when fully mature. The immature inflorescence (spadix) is covered in spathes. Randomly select true-to-type parents among the palms bearing inflorescences that are ready to open after a month, at the right stage for controlled pollination. CFC Technical Paper No. Store seed nuts in the shade to complete the maturation process. 1. Coconut hybrids for smallholders. The male flowers, which are on the top portion of spikelets attached to the peduncle, are more numerous than the female flowers, which occupy the base of the spikelets. The coconut is a monoecious plant producing male and female flowers separately on the same tree. There should be at least 45 palms per dwarf accession and 90 palms per tall accession and they must have been generated from at least 10 parent palms for dwarf accessions and 40 parent palms for tall accessions. Plant nuts close to one another and cover them with soil, with about two-thirds of their size buried to prevent them from floating in case of heavy rains. The major insect pests include the rhinoceros beetle (Oryctes rhinoceros (Linnaeus)), the palm weevils (Rhynchophorus spp. If using organic matter instead of mineral fertilizer, determine its mineral content before use to ensure that the palms are adequately fertilized. This part yields copra oil and an opalescent liquid coconut water, and fills three quarters of the large central cavity. source Flowers and fruit: Inflorescence 1-1.5 m long and branched to one order. CIRAD, COGENT, IPGRI. They are now almost ubiquitous between 26°N and 26°S except for the interiors of Africa and South America. The two main types of coconut palm are tall and dwarf. Gray, in Encyclopedia of Human Nutrition (Third Edition), 2013. The vascular sap collected from immature unopened coconut inflorescence is popularly known as Neera in fresh form. The Nair community of Kerala place a coconut inflorescence inside a wooden barrel filled with paddy grains as the auspicious centerpiece in the kalyanamandapam (traditional wedding podium) of the. Tall palms are normally cross-pollinating and heterozygous, while dwarf palms are normally self-pollinating and homozygous. Figure 7.3. Take fruit to the nursery straight away and store in the shade to complete the maturation process. Climatic and nutritional conditions during the flowering stage affect the relationship between the number of female flowers and ripe fruits obtained, or the fruit set rate. The fruits have no dormancy and so cannot be stored for long. Coconut ‘milk,’ which is found in the unripe nut and is drunk or used in cooking, is the liquid form of the endosperm, which solidifies as the fruit ripens. Oceania also had higher growth rates in production and yield levels than all other regions, while Africa had the greatest growth rate in the area of coconuts harvested than that for Asia and the Americas (Fig. The inflorescence develops within a strong, tough pointed double sheath called spathe. Apply fertilizer (NPK + Mg) 1 year after planting based on the results of leaf analyses, and every year after that. The smaller male flowers are at the tip of the inflorescence, while the larger female flowers are at the base. Contact Us. The native origin of the palm is uncertain, as the nuts were easily dispersed between both islands and continents by ocean currents and by early explorers. The meat of these coconuts, called copra, is often dried, ground and pressed for oil, and their fiber is spun into rope, or coir. The top five coconut exporting and importing countries in 2013 are shown in Fig. Coconut (Cocos nucifera; Arecaceae) is widely distributed in tropical regions of the world, ranging between 20° N and 20° S latitude. Tie the inflorescence with plastic twine and slowly pull them downwards. allergies popped up to cat's, dog's, coconut, and adhesive to name a few. I have had issues since my appendix surgery at 16yrs old. 7.6A–B, respectively. Harvest seed nuts every 2 months for tall accessions and every month for dwarf accessions. From: Industrial Crops and Products, 2015, Laura J. Pham, in Industrial Oil Crops, 2016. To bag the inflorescence, cut the spathe at the base, opening it first if it has not yet been done (in the case of autogamous plants). Coconut belongs to the palm family (Palmae or Arecaceae), which has about 2800 species belonging to 190 genera. Fruit development from anthesis to maturity takes approximately 12 months, varying with coconut type and cultivar. Santos GA, Batugal PA, Othman A, Baudouin L, Labouisse JP, editors. 4). B.A. The tall tree such as the Sri Lanka or West African tall can grow up to 25–30 m while the dwarf, such as the Malayan dwarf typically does not exceed 4–8 m in height. It is sweet and oyster white in colour and translucent. A. Gordon, J. Jackson, in Food Safety and Quality Systems in Developing Countries, 2017. For allogamous and partially allogamous varieties, bag the inflorescences on the day the spathe opens. Harvest seed nuts monthly, 11 months after pollination. In an early genetic engineering success, B. napus was engineered to produce oil with about 50% lauric acid through transformation with a cDNA encoding a lauryl-ACP thioesterase from the California bay laurel (Umbellularia californica) (Voelker et al., 1996). Taking care not to knock off the male flowers, fit the plastic bag over the inflorescence with the opening towards the base of the peduncle. Coconut (Cocos nucifera L.) is an important multipurpose perennial crop of the tropics. If possible, use different male and female parents. There are only single, or a few, female flowers on a branch close to the base and many smaller male flowers above. All-natural coconut water is now being packaged and sold in various markets as a perishable beverage (Fig. In this study, B. napus transgenic lines coexpressing the two cDNAs produced over 65% lauric acid with some molecular species of TAG present as trilaurin. The main axis is branched and numerous sessile flowers are enclosed in a large bract known as spathe. Thengin pookuladi Rasyanam is a fabulous medicine enriched with the nutrients of coconut inflorescence. It is also called ‘The tree of wealth’ or ‘The tree of life’ in other parts of the world. Spathe and inflorescence The coconut spathe is the scope-like structure that encloses the inflorescences (the flowers) of the tree. It is woody and perennial with a stem that is erect, unbranched and cylindrical and grows from a single shoot meristem at the apex of the plant. Mixed Inflorescence: In this case two or more types of inflorescence get mixed up to form a mixed … The male … 1978. The top of the trunk consists of a radiating compact crown with large, thick cuticled pinnate leaves. For example, 95% of yellow and red dwarfs are autogamous (self-pollinating) and the yellow or red colour of the sprout of the germinated seed nuts can be used as a genetic marker to eliminate off-types. Visit the field twice a week (young plantation) or once a month (adult plantation) to monitor and control pests or diseases. If the off-type is identified during the first two years after planting, replace it with legitimate material. (photo: Fonana Youssouf), Harvested coconut seednuts (photo: Fonana Youssouf). The male flowers number about 250–300 per spikelet. Type II (indirect partial autogamy): Short female phase with no overlap with the male phase of the same inflorescence but with considerable or total overlap with the male phase of the following inflorescence. (photo: Fonana Youssouf), Conditioning coconut pollen in a freezer. The exocarp and the mesocarp make up the husk of the coconut. Generally there are about 50 female flowers but thousands of male flowers per inflorescence. ), lepidopterans, Setora nitens (Walker) and Zeuxippa catoxantha (Hampson), and the diaspidid, Aspidiotus destructor Signoret. The familiar hard shell of the coconut is the endocarp, or inner layer, of the mature ovary of the fruit, and within the shell is the actual seed, covered with a thin brown seed coat. Coconut production share (A) and growth rate by region (B). The other is a soft eye having the embryo located underneath. Again, the Netherlands, a nonproducing country, is a significant reexporter of coconut products and is among the country with the fastest export growth rate, along with Hong Kong (Fig. It is claimed that they evolved to disperse significant distances via marine currents. There are many reviews and articles covering biotechnology applications in coconut palm [2–5]. Each of these 48 crosses is made twice, for a total of 96 controlled pollinations. The fruits of the palm mature in 12 months. Fruit-bearing starts after six years. Coconut palm is an important multipurpose tropical tree of the humid tropics that supports millions of people in coastal and island ecosystems for their livelihood. As the presence of the bag has a strong depressive effect on fruit set, do not bag the inflorescences too early. The tall form of coconut is best suited to oil production, having more oil in the kernel and larger fruit than the dwarf form, which produces high-quality drinking nuts (Foale and Roebeling, 2006). Examples are … Coconut provides a wide spectrum of human consumable products such as oil, kernel, tender nut water, toddy, neera, coconut sugar, immature inflorescence and haustorium. International Agricultural Research Centres who worked together to make this site possible: This is important because information on the number of female and male parents initially used in the controlled pollination program is not sufficient; some of these parent palms may not have living progeny in the field. Isolate the inflorescence at least 8 days before the female flowers start becoming receptive. Durée et succession des phases mâles et femelles chez divers types de cocotiers. (1996). Controlled pollination, in which an individual identified palm is crossed with designated individual female palms, is a labour-intensive and costly technique, requiring a well-organized and trained team of technicians, a well-equipped laboratory for pollen processing and supervision by an experienced researcher. For all other varieties (all tall types and the green dwarfs), use controlled pollination, with the requisite isolation, bagging and pollination of the inflorescences. If a ladder is used to climb the palms, this is when the palms become 10–12 m high (25–30 years old for tall types). Coconut is the “tree of life” as it plays a vital role, in addition to giving food, drink and shelter, in the economies of many small island countries in the Caribbean, Indian, and Pacific Oceans. French - Portuguese - Spanish. Cocos nucifera is a large palm, growing up to 30 m (100 ft) tall, with pinnate leaves 4–6 m (13–20 ft) long, and pinnae 60–90 cm (2–3 ft) long; old leaves break away cleanly, leaving the trunk smooth. Provide irrigation when rainfall is limiting or during the dry season when the water deficit is over 50 mm for the month. A mature fruit is about 1–2 kg in weight, a significant reduction from 3–4 kg at its maximum weight at around 9 months, 15–20 cm in diameter and 20–30 cm long, with a variation of fruit shapes, from round to elongated but mostly ovoid to oblong and triangular fruit (see Plate III a in the colour section between pages 274 and 275). Accessions are generally planted close to each other and surrounded by palms of many varieties. Dwarf coconut palms reach a height of 8–10 m in 20 years. It has five stamens. The coconut plant is monoecious with inflorescences bearing both male and female flowers. The seedlings are transplanted to the field after 8–10 months, when leaf splitting occurs. Konan J.L., Bourdeix R. and George M.L. 7.7A). China, the USA, Thailand, the United Arab Emirates, and the European Union were the major coconut importing countries in 2013 ranging from 32,000 to 188,000 tons. Figure 7.4. Each leaf measures 5–6 m in length and weighs 10–15 kg. When the tip of the unopened coconut inflorescence is cut out, the sap slowly flows out. To facilitate the identification of palm pedigrees, prepare a planting map where the plots are identified to show the spots where specific palms are to be planted. They are also monoecious. Also tie the sleeve with a rubber band and keep the plastic bag rolled up with tape. While in rural areas, dried fronds make good fuel for cooking and torch (sulô). By continuing you agree to the use of cookies. The plantations are usually located in the lowlands just above beach level. Les phases mâles et femelles de l’inflorescence du cocotier. In: Dulloo M.E., Thormann I., Jorge M.A. All the nuts collected per pollination and per inflorescence should be grouped together to avoid mixing of the seed nuts. Type III (direct autogamy): Long female phase completely overlapping with the male phase of the same inflorescence, with or without overlapping with the male phase of the following inflorescence. The palm produces an average of about 12 leaves annually. CGIAR System-wide Genetic Resource Programme, Rome, Italy. The main coconut producing countries are the Philippines, Indonesia, India, Papua New Guinea and the Pacific Islands. Many errors can occur with crosses from controlled pollinations and so the following controls should be put in place: Batugal PA, Ramanatha RV, Oliver J, editors. Rear seedlings in a well-maintained nursery to produce normal uniform plants. After planting, record the pollination numbers in a plot map and check again by verifying the male and female parent of each palm in the field to ensure that the correct pedigree is planted. 3. Indonesia, Philippines, India, and Sri Lanka are the major coconut-producing countries. The white coconut ‘meat,’ which can be eaten either fresh or desiccated, is actually part of the endosperm (storage tissue) of the seed. Coconut, Cocos nucifera L., is the only species in Cocos genus, within Aracaceae family, Cocoeae order. Top 5 exporting (A) and importing (B) countries for coconuts. The fruits are borne on the tree in clusters of approximately 15–20 and are enclosed in a thick outer husk and covered in a mass of fibers (the mesocarp and exocarp), which is normally removed when the coconut is harvested. It is anchored by numerous adventitious roots which are produced from the swollen basal part of the stem. 7.7B). 7.4B). Coconut varieties are classified into four groups according to their mode of reproduction: Type I (strict allogamy): Short female phase with no overlap with the male phase of the same inflorescence or with the male phase of the following inflorescence. Figure 7.5. Coconuts in various stages of maturity on a tree. It is very important that no female flower should be receptive at the time of bagging. Examples are the cultivars Rennell Island Tall, Malayan Tall, Vanuatu Tall. The nursery should be open, level and well-drained with light or loose-textured soil and far from sources of insect pests and diseases. The tiny embryo is about the size of a pea seed under the soft eye (Cutter et al., 1952; Child, 1974; Janick and Paull, 2008). For most tall-type coconut cultivars, leaves turn a golden yellow before dying (Figs. There are two distinctively different forms of the coconut fruit, known as niu kafa and niu vai, Samoan names for traditional Polynesian Keep extra seed nuts from the controlled pollinations for back up as only about 65% will result in seedlings for transfer to the field. Manual on Standardized Research Techniques in Coconut Breeding. Surround the peduncle of the inflorescence with a wad of cotton impregnated with insecticide and spray the inflorescence with an insecticide. Coconut Data Management (CDM) manual, version 3. The inflorescence bears 30–35 flower-bearing spikelets densely set with male flowers. Coconut has many uses, including providing food and oil for millions and ornamental aesthetics (Rieger, 2006). Until yesterday when I found your blog I thought I was allergic to another unidentified something. Coco sugar is fast becoming unaffordable here in the Philippines because it is being exported to Japan where the demand is very high. 7.5A–B). Talls should be planted at a density of 143 palms/ha with a spacing of 9m between palms and 7.5m between rows. That was in bath washes and laundry soaps. Set out the polybagged seedlings in the same order as they germinated. In other words, they consist of male and female flowers on the same inflorescence (spadix) that develops within a woody spathe. Positional analysis of fatty acyl groups in the TAGs of these transgenic lines, however, revealed very little accumulation of lauric acid at the sn-2 position, likely due to a limitation in the specificity of the indigenous LPAAT which catalyzes the acylation of the sn-2 position of lysophosphatidic acid (LPA) to generate PA in the G3P pathway leading to TAG (Snyder et al., 2009). Figure 7.6. 7.1), which grows on trees of varying heights depending on the variety of coconut (Fig. The coconut palm is diploid (2n=32). 7.3). Figure 7.7. In the Philippines, it is common incision to remove the coconut inflorescence plastic, this plastic is fermented to produce palm wine, also known as tuba. Replace plants which have lost their pollination numbers during transfer to the field with others of known pedigree. 1996. This way only the controlled pollinated nuts will develop and errors will be eliminated. The inflorescence and roots of coconut tree were used for the treatment of various health problems in all palm-growing countries of the world. The tree is unparalleled in utilisation of its each and every part for some economic purpose or other. So, it is necessary to have labels that can withstand time and vagaries of weather. Examples are the Brazil Green Dwarf and many dwarf x tall hybrids. Cocos nucifera is one of the most adaptable products which possess several protein fractions such as albumins, globulins, prolamines, glutelins 1 and 2 which were found and reported. 2009. McVetty, ... Randall J. Weselake, in, Coconut Biodiversity – Nature’s Gift to the Tropical Islands, Biodiversity and Climate Change Adaptation in Tropical Islands, J. Siriphanich, ... S. Tongchitpakdee, in, Postharvest Biology and Technology of Tropical and Subtropical Fruits: Cocona to Mango, Case study: application of appropriate technologies to improve the quality and safety of coconut water, Food Safety and Quality Systems in Developing Countries, Encyclopedia of Human Nutrition (Third Edition). When flowering lasts for 3–4 days and the female flowers are receptive for 2 days, one pollination is sufficient (this is the case with tall cultivars). Coconut Genetic Resources. Specimens have been collected from the sea as far north as Norway (but it is not known where they entered the water). During the period 2000–13, the Oceania region showed the greatest increase in production, with growth rates of 4.6%; this was followed by Asia at 1.5%, the Americas by 1.1%, and Africa by 0.7% (FAOSTAT, 2014). by clicking on the picture above (0.2MB), Also available in the following languages: its inflorescence carries both male and female flowers. If technicians can climb the coconut without a ladder, there is no such limit, and the accessions could be conserved for at least 50 years, if there are enough living palms. Examples are the cultivars Malayan Yellow Dwarf, Sri Lanka Green Dwarf and Cameroon Red Dwarf. Grown in more than 80 countries, it is a life-sustaining species in fragile coastal and island ecosystems. Detect off-types by their special traits, e.g. The fruit is a drupe containing a single seed. The Inflorescence The coconut inflorescence is enclosed in a double sheath or spathe, the whole structure known as a 'spadix' which is borne singly in the axil of each leaf.
