The potassium salt of NAA is the active compound in plant growth regulators such as K-Salt Fruit Fix which is registered and used to control preharvest drop of apples and pears and for thinning of apples, olives, citrus and pears. True male and the functionally male flowers are the pollen sources during pollination and for good fruit set. Propagation through seeds, patch budding and grafting. Maturation of terminal shoots is non-synchronous in Hawaii, therefore maturation of terminals does not often coincide with the onset of water stress periods.Publications, Progress 10/01/03 to 09/30/04OutputsRambutan cultivars responsive to the potassium salt of naphthalene acetic acid (K+NAA) were identified, by treating cultivars (Binjai, Jitlee, R162, R167, R9, R134, R137 Red, R156 Red, Rongrien, R7, and R156 Yellow) with 90 ppm of K+NAA between June and September. An extended flowering season will prolong the harvesting season. Longan comes from the Chinese word longyan, meaning “dragon eye” since its translucent flesh and black seed resembles an eyeball. Sometimes depending on the weather conditions, a small harvest is gathered during December to February. When ripe, it can be halved and eaten with a spoon, while many choose to enjoy it with sticky rice and coconut milk (Khao Niew Ma-Muang).Others like to eat it half-ripe and dip the crunchy slices in sugar. Cook the flesh, softened seeds, and 1½ cups (or 350g) sugar. 5 (2019). The blooming of all flowers in an inflorescence takes about 24 days (Tongumpai, 1980). Panicles were treated at 10% anthesis with 90 ppm and retreated with the same concentration 8 days after the first application when approximately 50% of the flowers had opened. It is native to Malaysia, where it is commonly cultivated for its tasty fruit, also called rambutan. As trees mature they settle to one main fruiting per year and a window of 3 to 5 months of harvest. Abstract: Update of tropical fruit crop research. RAMBUTAN FLOWERS. Panicles were treated at 10% open and retreated 8 days later when approximately 50% of the flowers were open. Silengkeng, a cultivar originally from Indonesia, will naturally produce more male flowers than other cultivars and has a prolonged anthesis period that can extend over 4 months. It is best eaten when it is bright red in color, which means it’s ripe and sweet. The fruit is a round to oval single-seeded drupe, 3–6 cm (rarely to 8 cm) long and 3–4 cm broad, borne in a loose pendant cluster of 10–20 together. Observations also revealed that panicles with a more robust appearance were more responsive to NAA and that individual flowers responding to the K+NAA were those where the tip of the flower was beginning to open and the white tip of the pistil was just visible. The duration from fruit set to harvest is 1416 weeks. Low humidity levels, storage time, and incidences of mechanical damage can severely affect the quality of the fruit which would negatively affect the demand of such. Nonetheless, by switching between sources and microclimates, importers are able to offer a rambutan supply from South-East Asia twelve months a year. Rambutan grows well from sea level to medium altitudes in places with a long rainy season. IR4 registration for NAA use on rambutan is being pursued.Publications, Progress 10/01/04 to 09/30/05OutputsA multi-year phenology study on rambutan (Nephelium lappaceum) trees in Hawaii is nearing completion and has shown that flowering occurs on mature terminals approximately 1-2 months after a period of water stress. [3] In the Malay peninsula, commercial varieties include 'Chooi Ang', 'Peng Thing Bee', 'Ya Tow', 'Azimat', and 'Ayer Mas'.[3]. of functionally male flowers and can be planted in the orchard as a pollinator tree. Mangosteen caterpillar. Rambutan trees exhibit strong apical dominance and have a tendency to produce long, upright growth. Flushing typically occurs 3-4 times yearly It is on the red-peel and green-fibre variety that most of the supply is based, with in particular the Rongrian cultivar very common in Thailand and now in Vietnam. Several attempts on flowering induction show significant results in regulating off-season production of mango (Mangifera indica L.), mangosteen (Garcinia mangostana L.), durian (Durio zibethinus Murr.) After harvesting, fruited twigs are pruned back to stimulate new growth of up to 4 new side shoots, of which 22% of the shoots will bear fruit in the following season. The flowers bloom twice locally, in April to May and September to October. In 1912, rambutan was introduced to the Philippines from Indonesia. 10-12 weeks after anthesis. An annual rambutan fair is held during August harvest time.[18]. At harvest BRIX readings for the aril are 18% or greater. Certain treatments like irradiation and the use of hot-forced air can help in fruit preservation although the former has seen more success. Well over 200 cultivars were developed from selected clones available throughout tropical Asia. Hilo, Hawaii. Rambutan can be propagated through seed, (which takes about 10-15 days to germinate) marcotting, inarching, cleft grafting and patch budding. These panicles treated produced male flowers at 4 days after treatment. Male flowers were visible in about 4 [4] The flowers are receptive for about one day, but may persist if pollinators are excluded. Most commercial cultivars are hermaphroditic; cultivars that produce only functionally female flowers require the presence of male trees. 12 p. Nagao, M.A., Leite, H.M., Hara, A.H. and Niino-Duponte, R.Y. Fruit of Rambutan: The fruit will be round in shape, it contains a single oval seed, and the fruit will be 3 cm – 6 cm in length and 3 cm – 4 cm in broad. Remove the skin and seeds before eating! code BTGOPLANT Free Shipping above 399. code FREESHIP Images are for reference purposes only. The Si Chomphu variety, with its highly iconic yell… To determine if K+NAA was successful in inducing male flowers when panicles were at an advanced stage of anthesis, Jitlee panicles were treated when approximately 50% of the flowers had initiated or completed anthesis. Kawabata, A.M., Nagao, M.A., Aoki, D.F., Hara, K.Y.and L.K. Late-summer and winter harvests are typical. Place your rambutan tree in partial sun. Yearly flowering in Hawaii is split between the two induction periods. Rambutan trees can be male (producing only staminate flowers and, hence, produce no fruit), female (producing flowers that are only functionally female), or hermaphroditic (producing flowers that are female with a small percentage of male flowers). The growth cycle of ‘Java’ rambutan is about 9.5-10 months. Tropical Fruit Conference. [4] Soft and containing equal portions of saturated and unsaturated fats,[10] the seeds may be cooked and eaten. [3][4], The name "rambutan" is derived from the Malay word rambut meaning "hair", a reference to the numerous hairy protuberances of the fruit, together with the noun-building suffix -an. [citation needed] In Thailand, a major cultivation center is in Surat Thani Province. In 1912, rambutan was introduced to the Philippines from Indonesia. Rambutan . days. Not only good when eaten directly, but rambutan can also be made into a fresh dessert, rambutan setup ice.

A typical tree has fruit ripening continuously over a 30 to 50 day period. The rambutan is native to Southeast Asia. Bananas, sprouted coconuts, yellow dragonfruit and soursop are almost always available year-round. Male flowers have yellow nectaries and five to seven stamens. Furthermore, the spines (also known as spinterns) contribute to the transpiration of the fruit, which can affect the fruit's quality. days after the second treatment, or 15 days after the first spray application. Fruits exhibit a simple sigmoid growth curve with the rapid growth period occurring between 10 and 16 weeks after anthesis. The pedicels are thin, greenish yellow and densely rusty pubescent. The fruit are usually sold fresh and have a short shelf-life,[11] and are commonly used in making jams and jellies, or canned. They are in season from August to October. Rambutan roots, bark, and leaves have various uses in traditional medicine[3] and in the production of dyes. and rambutan … Yearly flowering in Hawaii is split between the two induction periods. Rongrien and Jitlee consistently produced male flowers, and anthesis occurred more synchronously than with other cultivars. Flowers that were entirely closed and those with a fully exposed stigma were not responsive. I hope it will be another good crop season. Rambutan yield increased 7.6-16.1% compared to the farmer’s Pollen grains from 11 cultivars were tested for viability along with pollen from naturally produced male flowers of Silengkeng and pollen from flowers of a male tree. Since some fruits ripen multiple times of the year, it is hard to be precise. Although male flowers open at 06:00, foraging by A. cerana is most intense between 07:00 and 11:00, tapering off rather abruptly thereafter. Proceedings of the 13th Annual International Tropical Fruit Conference. Sri Lanka also has some off-season rambutan production in January and February in areas such as Bibile, Medagama, and Monaragala. Usually, a single light brown seed is found, which is high in certain fats and oils (primarily oleic acid and arachidic acid)[10] valuable to industry, and used in cooking and the manufacture of soap. Seed filling begins 8 to 10 weeks after anthesis and aril (flesh) development occurs 10-12 weeks after anthesis. So, several harvesting intervals of 2 to 7 days are common during the season. Vegetative flushing can occur in response to a significant amount of rainfall, harvest, or pruning. (Available high and low season.) Rambutan . 15th Annual International Tropical Fruit Conference. Rambutan, longan and lychee are all part of the soapberry family. The rambutan is a fine-looking tree with a fairly straight trunk, which can reach a height of 10 to 15 metres. Production of male flowers peaked 6 to 8 days after the treatment and gradually ceased after about 12 days. These results indicate that a second application of 90 ppm K+NAA prolonged the formation of male flowers by approximately 3 days. Collection of data for registration of NAA through the IR4 program is underway.ImpactsRambutan flowering in Hawaii can occur during spring and summer, thus growers in Hawaii can produce 2 crops over a 12 month period. Pollinators may maintain a fidelity to either male or hermaphroditic flowers (trees), thus limiting pollination and fruit set under natural conditions where crossing between male and female flowers is required. [19] In Indonesia, 22 rambutan cultivars were identified with good quality, with five as leading commercial cultivars: 'Binjai', 'Lebak Bulus', 'Rapiah', 'Cimacan' and 'Sinyonya', with other popular cultivars including 'Simacan', 'Silengkeng', 'Sikonto' and 'Aceh kuning'. The main harvest season is in winter between December and January with a second minor harvest season in late-summer (August to September). Initial fruit set may approach 25 percent, but a high abortion level contributes to a much lower level of production at harvest (1 to 3 percent). Flowering Season: Harvesting Season: Thailand: Late December - Late February: Late June - Late August: China: Late February - Early April: Late July - Late September: Taiwan Province of China: February - April: July - October: Australia: August - October (North Queensland) October - November (Southeast Queensland) Mid-January to Mid-March Late February to Early April Hermaphroditic functionally female flowers, which develop into fruits and number between 200 and 800 on each panicle, do not shed pollen since the anthers do not dehisce. If seeds are planted, some seedlings develop into male trees that possess only true male flowers. In some areas, rambutan trees can bear fruit twice annually, once in late fall and early winter, with a shorter season in late spring and early summer. Little or no male flowers were produced on untreated panicles for all cultivars. Rambutan is propagated by grafting,[17] air-layering,[17] and budding. Flowering is split between the two induction periods and can occur in spring (April to May) or in summer (July to August) which is the principal flowering period. These 2 characteristics make it a good pollinator tree for orchards. Both male and female flowers are faintly sweet-scented and have functional nectaries at the ovary base. HM are less common during cooler months and resemble HF, but HM anthers shed pollen at anthesis. The optimum concentration of K+NAA required for development of male rambutan flowers at 7 days after treatment was a 90 ppm concentration. Late-summer and winter harvests are typical. Rambutan (scientific name: Nephelium lappaceum) is a tropical evergreen tree and fruit tree of the genus Nephelium in the family Sapindaceae, native to Southeast Asia. [4] It is grown commercially within 12–15° of the equator. They were in 3 gallon containers and about 3-4 feet tall. Little flushing occurs during winter months even in the presence of high precipitation.ImpactsFlowering of rambutan trees in Hawaii occurs on mature terminals approximately 1-2 months after a period of water stress. Hawaii has 2 harvest seasons. [3] Further introductions were made in 1920 (from Indonesia) and 1930 (from Malaya), but until the 1950s its distribution was limited. Maturation of terminal shoots is non-synchronous in Hawaii, therefore maturation of terminals does not often coincide with the onset of water stress periods. Rambutan trees should be sheltered from strong winds which do much damage during the flowering and fruiting periods. Budded trees may fruit after two to three years with optimum production occurring after eight to 10 years. The main harvest season is in winter between December and January with a second and more minor harvest season in late-summer (August to September). The trees are prolific, producing hundreds of fruits in a season, but Rambutans are easily bruised and must be harvested by hand, cut in clusters to prevent the rind's tearing. Harvesting occurs at 16 to 20 weeks after anthesis, and at harvest BRIX for the aril is 18% or greater. The fragile fruit must ripen on the tree, then they are harvested over a four- to seven-week period. Flowering can occur during the spring (Apr to May) and summer (Jul to Aug), thus trees encounter flower induction conditions during January to February and during June and July. The red oval fruits are … Ringing was done by completely removing 2 cm … Rambutan flowers have pleasant aroma with white color and 3-5 mm long. The rambutan on basaltic red soil in Dong Nai province, with the formula of 1.0 kg N + 1.2 kg P 2O 5 + 1.5 kg K 2O + 15 kg manures/tree/season and Growmore foliar fertilizer 20-20-20, spraying 2 times/season gave best result. Vegetative flushing typically occurs 3-4 times yearly with pronounced flushing in May and smaller flushes in August and November. Vegetative flushing can occur in response to a significant amount of rainfall, harvest, or pruning. Rambutan fruit contains diverse nutrients but in modest amounts, with only manganese having moderate content at 16 percent of the Daily Value per 100 g consumed (right table; note data are for canned fruit in syrup, not as raw which may have different nutrient contents). Cupping of the terminal leaves is evident when trees are exposed to sufficient water stress for flower induction. [11] It is a popular garden fruit tree and propagated commercially in small orchards. To determine the optimum concentration of K+NAA Impacts Flowering of rambutan trees in Hawaii occurs on mature terminals approximately 1-2 months after a period of water stress. For the cipher, see. 2003. Anthesis in an orchard occurs over 2 to 3 months, and harvesting occurs 16 to 20 weeks after anthesis when BRIX readings are 18% or greater. The rambutan (/ræmˈbuːtən/, taxonomic name: Nephelium lappaceum) is a medium-sized tropical tree in the family Sapindaceae. The rainfall should be fairly well distributed throughout the year, although a short dry season is tolerated and may induce flowering. The rambutan is a rich source of vitamins and minerals that aids in losing weight, strengthening bones, and also offers anti-parasitic properties. It grows on hilly terrain where there is good drainage. Panicles on grafted rambutan cultivars possess hermaphroditic functionally female flowers (HF) intermingled with a very small percentage (<1.0%) of hermaphroditic functionally male flowers (HM). These results show that a second application of 90 ppm K+NAA can prolong development of male flowers by approximately 3 days.Publications, Progress 10/01/02 to 09/30/03OutputsPreviously we demonstrated that fruit set of rambutan in Hawaii is often limited by the absence of male flowers within the orchard and sufficient pollen to obtain good fruit set and normal fruit development. [14], Rambutans are not a climacteric fruit — that is, they ripen only on the tree and appear not to produce a ripening agent such as the plant hormone, ethylene, after being harvested. Up to 100 flowers in each female panicle may be open each day during peak bloom. Cross-pollination is a necessity because the anther is absent in most functionally female flowers. [3] Most of the cultivars are also selected for compact growth, reaching a height of only 3–5 m for easier harvesting. Pineapples are in season from May to July. The proper method of irrigation is needed according to the age and yield of trees. [10], The pleasant fragrance of rambutan fruit derives from numerous volatile organic compounds, including beta-damascenone, vanillin, phenylacetic acid, and cinnamic acid. The flowers are small, 2.5–5 mm, apetalous, discoidal, and borne in erect terminal panicles 15–30 cm wide.[4]. Viability of pollen grains from NAA induced male flowers was determined with a pollen germination medium containing , 50 ppm H3BO3, 150 ppm Ca(NO3)2 4H2O, 100 ppm MgSO4 7H2O, 50 ppm KNO3 and 5% Sucrose. [citation needed] Some of these farmers saw the first production of rambutan from their trees in 2005–2006 with development directed at the local market. If seeds are planted, some develop into male trees that never fruit and possess only true male flowers (TM). Panicles with a more robust appearance were more responsive and flowers responding to the K+NAA were those where the tip of the flower was beginning to open and the white tip of the pistil was just visible. The rambutan usually grows in clusters with the color of yellow, orange or red, which is somewhat like how lychee grows. Its outer skin is red with soft yellowish & neon green prickly pokers all around it. Among the Diptera, Lucilia spp. In the Philippines, flowering occurs from late March to early May while the fruiting season is from August to October. The aril is attached to the seed in some commercial cultivars, but "freestone" cultivars are available and in high demand. The data showed that male flower production peaked about 9 days after the first treatment, and their production ceased about 7 Excessive rainfall during the expected flowering season is detrimental to flowering and encourages vegetative growth. A series of experiments were conducted to determine whether the potassium salt of NAA (K+NAA), which is highly soluble in water, could be as effective as the acid form for stimulating male flower development. Top End horticulturalist, Greg Owens, said some farms have had up to three separate flowering events. There was an attempt to introduce rambutan to the southeastern United States, with seeds imported from Java in 1906, but the species proved to be unsuccessful, except in Puerto Rico. Also, rambutan trees like to stay moist. Cultivars were located in East Hawaii and situated on rocky Aa to silty clay loam soils and elevations between 75 to 250 m. Panicles were sprayed to runoff with K+NAA when approximately 10% of the flowers were at anthesis. The bark is known to cure sores. [citation needed] The common rambutan seed and fruit are difficult to separate, while the 'Maharlika Rambutan' fruit separates cleanly from its seed. Because panicles on grafted rambutan cultivars possess functionally female flowers intermingled with a small percentage (<1.0%) of functionally male flowers, development of deformed fruits lacking a fleshy aril is a common problem in Hawaii due to poor pollination. The experiment was conducted at the local orchards in Cha-oat district, Nakhon Si Thammarat province from July, 2011 to January, 2012 for off-season flower induction of 'Rongrien' rambutan production in Thailand. [5], The center of genetic diversity for rambutan (indicating its possible origin) is Kalimantan, the Indonesian portion of the island of Borneo. Flowering induction show significant results in regulating off-season production of mango, mangosteen , durian and rambutan. The majority of the world's rambutan production occurs in Malaysia, Thailand, and Indonesia, where the climate is highly influenced by yearly monsoons. An extended flowering season will prolong the harvesting season. Most, but not all, flowers open early in the day. Harvesting occurs 16-20 weeks after anthesis when BRIX readings are 18% or greater. Male flower production was apparent 4 to 5 days after treatment. Rambutan season has started!!! As an unpigmented fruit flesh, rambutan does not contain significant polyphenol content,[20] but its colorful rind displays diverse phenolic acids, such as syringic, coumaric, gallic, caffeic, and ellagic acids having antioxidant activity in vitro. initiate flowering and stimulate flower bud growth (Salakpetch, 2005). Etymology. In Thailand, rambutan trees were first planted in Surat Thani in 1926 by the Chinese Malay K. Vong in Ban Na San. Since In some areas such as Malaysia, rambutan trees can bear fruit twice annually, once in June and with a shorter season ending in December. Their production comes to market in May, June, and July, when it is very common to observe seasonal traders along the streets of Colombo. About 500 greenish-yellow flowers occur in each hermaphroditic panicle. Rambutan cultivation in Sri Lanka mainly consists of small home gardens. Deformed, undersized fruits that lack a fleshy aril will be a common occurrence without pollination. 2 p. Nagao, M.A., Leite, H.M., Hara, A.H., Kawabata, A.M., Terada, A.Y., Salakpetch, S. and Chandraparnik, S. 2002. Grafted or air layered male trees planted within or around the perimeter of an orchard will also increase availability of pollen during flowering. Origin and distribution. Rambutan trees are prolific producers of flowers, but the number of flowers that set fruit is low (Kosiyachinda and Salma, 1987). Rambutan (Nephelium lappaceum) is a medium-sized tropical tree growing to a height of 12–20 m.The leaves are alternate, 10–30 cm long, pinnate, with 3-11 leaflets, each leaflet 5–15 cm wide and 3-10 cm broad, with an entire margin. The flowering process is the critical point for the fruit production. Female flowers produce two to three times more nectar than male flowers. Progress 10/01/02 to 09/30/06OutputsRambutan flowering in Hawaii occurs on mature terminals approximately 1-2 months after a period of water stress. To overcome this problem, Silengkeng, an Indonesian cultivar, should be inter-planted in the orchard since it naturally produces more male flowers than other cultivars and has an anthesis period that can extend over 4 months. Rambutan can flower at any month of the year, so small amounts of fruit may be available throughout the year. However, there is a peak flowering period. [6][7] It has spread from there to parts of Asia, Africa, Oceania, and Central America.[8]. [3] There are limited rambutan plantings in some parts of India.
