THE EFFECT OF AQUILARIA MALACCENSIS SEED PRIMED WITH GIBBERELLIC ACID AND INDOLE BUTYRIC ACID

Abstract

The main goal of this study was to produce seedlings of Aquilaria malaccensis with rapid growth, uniformity and high quality. The effect of indole butyric acid (IBA) and gibberellic acid (GA 3 ) at different concentrations and combinations (100, 150 and 200 ppm) on the germination and development of seedlings was investigated. The primed seed was grown in two types of soil, namely, sterile and unsterile soil. The seeds primed with IBA ( 100, 150 and 200 ppm) and planted in sterile soil showed germination and organ development of 8 seeds from 3 treatments within 4–7 days. However, the seeds primed with GA 3 took 10 to 15 days for germination, and organ development of 14 seeds from 3 treatments. The germination rate of all the primed seeds of IBA and GA 3 grown in unsterile soil was null. The various combination of IBA and GA 3 played a significant role in the germination and organ development of A. malaccensis seed in the sterile soil (17.305 ± 0.88), than in unsterile soil.
