For example, in Singapore the strong demand for high quality cultivars such as the D24 (Sultan), and Musang King (Mao Shan Wang) has resulted in typical retail prices of between S$8 to S$15 (US$5 to US$10) per kilogram of whole fruit in 2007. [83] The traditional method to counteract this is to pour water into the empty shell of the fruit after the pulp has been consumed and drink it. The durian tree, reaching 90 to 130 ft (27-40 m) in height in tropical forests, is usually erect with short, straight, rough, peeling trunk to 4 ft (1.2 m) in diameter, and irregular dense or open crown of rough branches, and thin branchlets coated with coppery or gray scales when young. Its leaves are oval or lance-head-shaped and arranged alternately. These trees do not bear fruit every year. A naturally spineless variety of durian growing wild in Davao, Philippines, was discovered in the 1960s; fruits borne from these seeds also lacked spines. In Malaysia, 100 types are graded for size and quality. They used to be grown with mixed results from seeds of trees bearing superior quality fruit, but now are propagated by layering, marcotting, or more commonly, by grafting, including bud, veneer, wedge, whip or U-grafting onto seedlings of randomly selected rootstocks. The fruit can grow as large as 30 centimetres (12 inches) long and 15 cm (6 in) in diameter, and it typically weighs 1 to 3 kilograms (2 to 7 pounds). Due to the large number of species in this area, Ketapang Regency is a main region where durian is spread. 1, a cultivar without the characteristic odour. Malaya has two fruiting seasons: early, in March and April; late, in September and October. The trunks are straight and about 4 feet in diameter and can form buttresses. [30], Known locally as "durian IOI", this variety has a round shape, medium size, green and yellow outer skin colour, and has flesh easy to dislodge. In-season durians can be found in mainstream Japanese supermarkets, while in the West they are sold mainly by Asian markets. The durian has a high rate of self-incompatibility. A common saying is that a durian has eyes, and can see where it is falling, because the fruit allegedly never falls during daylight hours when people may be hurt. In unopened flowers the style is 1/3 as long as in fully opened flowers and the pollen reaches the ovules more quickly. [71], The durian is commonly known as the "king of fruits",[5] a label that can be attributed to its formidable look and overpowering odour. Barrett described the flavor as "triplex in effect, first a strong aromatic taste, followed by a delicious sweet flavor, then a strange resinous or balsam-like taste of exquisite but persistent savor." Seedlings make more vigorous growth when potted into media that is light and sandy rather than high in clay content. When the shoots are old, the fertilizer dosage given is 335 grams of urea, 36 365 grams, and 265 grams of KCl. In peninsular Malaya, there are 44 clones with small differences in time and extent of flowering, floral and fruit morphology, productivity and edible quality. The height of the durian trees ranges from 25m (80ft) to 50m (160ft). Most cultivars have a common name and a code number starting with "D". [10] Since the bases of the scales develop into spines as the fruit matures, sometimes spineless durians are produced artificially by scraping scales off immature fruits. Inside there are five things like elongated oranges, and resembling thick butter, with a combination of flavours. [51], The fruit's strong smell led to its ban from the subway in Singapore; it is not used in many hotels because of its pungency. These features are typical of flowers pollinated by certain species of bats that eat nectar and pollen. Seeds washed, dried for 1 or 2 days and planted have shown 77-80% germination. Wearing a hardhat is recommended when collecting the fruit. The flesh is mostly eaten fresh, often out-of-hand. [44] In fact, to eat Durians is a new sensation worth a voyage to the East to experience. [3][44][45], This strong odour can be detected half a mile away by animals, thus luring them. "[47] He cites another writer: "To those not used to it, it seems at first to smell like rotten onions, but immediately after they have tasted it they prefer it to all other food. [20], Durian flowers are large and feathery with copious nectar, and give off a heavy, sour, and buttery odour. The upper surface is smooth and glossy. The fruit is also placed as bait for game in the forests. You probably wouldn’t want this plantstrocity towering directly over your house, dropping durians down your chimney or bombing the cat. [38] Due to the increasing popularity of durian in China, the price had risen up to 20 times over in four years, in a market that was worth nearly £400m in 2018. [23] With an average weight of about 1.5 kg (3 lb 5 oz), a durian fruit would therefore cost about S$12 to S$22 (US$8 to US$15). [78] Strong nylon or woven rope netting is often strung between durian trees in orchards, serving a threefold purpose: the nets aid in the collection of the mature fruits, deter ground-level scavengers, and prevent the durians from falling onto people. Durian trees have one or two flowering and fruiting periods per year, although the timing varies depending on the species, cultivars, and localities. So you need room. [19] The fruit of many species has never been collected or properly examined, however, so other species may have edible fruit. Durian seeds lose viability quickly, especially if exposed even briefly to sunlight. [24] Since the 1920s, there have been more than 100 registered cultivars in Malaysia,[25] and by 1992 there were up to 193;[26] many superior cultivars have been identified through competitions held at the annual Malaysian Agriculture, Horticulture, and Agrotourism Show. The various preferences regarding ripeness among consumers make it hard to issue general statements about choosing a "good" durian. Durians mature in 3 1/2 to 4 1/2 months from the time of fruit-set. It is found wild or semi-wild in South Tenasserim, Lower Burma, and around villages in peninsular Malaya, and is commonly cultivated along roads or in orchards from southeastern India and Ceylon to New Guinea.
