1. INTRODUCTION

The durian is believed to be native to Borneo and Sumatra. It is a tropical lowland fruit and found wild or semi-wild in South Tenasserim, Lower Burma and around villages peninsular Malaya and is commonly cultivated along roads or in orchard. Although it is planted on a small scale, commercial production is mostly in Thailand, Malaysia, Indonesia, Philippines and Vietnam. The durian tree, reaching 27- 40 m in height in tropical forests, is usually erect with short, straight, rough, peeling trunk to 1.2 m in diameter and irregular dense or open crown of rough branches. Its leaves are oval or lance-head-shaped and arranged alternately. The upper surface is smooth and glossy. The lower part is covered with scales and hairs. Flowers are perfect, whitish, with a strong odor, cauliflorous (produced directly on large branches), clusters of 3-30, blooming at night and primarily pollinated by bats. The fruit is green to brown in color, pendulous, round to oblong in shape and is completely covered with strong sharp thorns. It is a capsule which splits into five parts when ripe, and each segment contains brown seeds covered with a thick, firm, and creamy-yellow pulp with an overpowering aroma. Because of this, the durian is known as “king of fruits”.
