Induksi Tunas Tanaman Gaharu (Aquilaria malaccencis Lamk) dengan Menggunakan Kombinasi Zat Pengatur Tumbuh BAP dan IAA secara In Vitro

Abstract

Agarwood (Aquilaria malaccensis Lamk.) is one of the important tropical forest trees, which produces a high economically valuable fragrant resinous wood. The increase of agarwood demand from year to year leads to uncontrolled illegal harvest of this plant from its natural habitat. To encounter this problem, there is an urgent need to develop agarwood plantation. The pusrpose of this research is to determine of combination concentrate the best growth regulators for shoot induction of agarwood. The methode used is complete random with four treathments and three replicanst. The results showed that combination growth regulators BAP and IAA make real influence such as life percentation, time of shoot induction, total shoot, and long shoot. At the same time for parameter total leaf, combination concentrated BAP and IAA has not a real influence. The treatment of growth regulators BAP 1.0 ppm and IAA 0.5 ppm is the optimum and the best concentrated in produce total shoot, long shoot, and total leaf of agarwood.
