Durian Facts
Durian Tree

The durian, scientifically known as Durio zibethinus Murr. is believed to originate from the Borneo Islands. This plant then spread to other tropical Asian countries like India, Sri Lanka, Myanmar, Thailand, Malaysia, Indonesia, Philippines and Papua New Guinea. Now, the durian is also grown in Australia. However, the main distributors are Thailand, Malaysia and Indonesia.

The Tree

Durian Tree - view from bottomIt is a large-sized tropical fruit tree. The tree can reach a height of 35 45m if grown from seeds. Trees that originate from seeds have a buttress at the lowest part of the bark. Durian trees that are planted on a smooth level of land are smaller in size (10-15m in height) and rarely have buttress roots at the lowest part of the tree.

When the durian is planted too close to other fruit trees, its canopy would form an irregular shape. In a plain field, durian trees usually have canopies the shape of a pyramid and is wide.

Leaf

Durian LeafThe durian is an evergreen tropical tree. The leaf measures 6-12 cm long and 2-4 cm wide. It ranges from pale green to dark bronze, with a glossy upper surface, and reddish-brown fine scales on the lower surface.

Flower

Flowers grow in clusters of 40-50 on the strong main mature branches. The number varies depending on the age and the size of a tree, and also on the surrounding environmental factors. Generally, flowers appear only once in a year.

Flower bud and flower

The flower bud is covered with fused epicalyx. The calyx has 4-6 lobes and there are five yellow petals. The nocturnal durian flower blooms when night falls and is at its peak at midnight. Usually, no pollen can survive until the next morning, so active pollination occurs during the night.

Bats
Bats are pollination agents


Among the pollination agents are bats(Eonycterus spalee and Macroglossus minimus), spiders(Apisdorsata) and ants.

Fruit

The durian fruit is usually round or oval and it is 20 25 cm in length and 18 20 cm in diameter. The fruit weighs from 1.0 4.5 kg. It has a thick skin and sharp thorns. Its stem is cylinder in shape and is 3 6 cm long. Its skin colour is usually green or yellowish green. The fruit has five sections. Each section contains a few pips (the durian seed is covered with flesh).

The durian pips differ in aspects like colour, thickness, texture, aroma, taste or flavour depending on the clone. The seed is oval-shaped and has a diameter of 11.5 cm and is chocolate in colour. Durian that has fallen off the tree cannot be kept long (just for 2 3 days).
