Abstract

Under the tropical climate of Sarawak, Edaw longan trees can be induced to flower while flowering intensity of free-flowering Diamond longan can be improved by application of chemical agents such as potassium chlorate, sodium chlorate and 'Vita-min'. The use of sodium chlorate is recommended as it is easily available and the cheapest one to use. It can be applied as a soil drench at a rate of 15g per m2 canopy. The best time of application is when trees have shoots of mature leaves with sign of new flushes. With this technology, cultivation of longan especially the high quality Edaw cultivar in the State can be promoted and encouraged to cater for domestic demand.
