Determination of Seeds Pre-treatment Method of Saga Pohon (Adenanthera sp.)

Abstract

Saga pohon ( Adenanthera sp.) seeds, have very hard seed coat and therefore to break seed dormancy pre treatment is needed. The purpose of this research is to investigate the effective method of breaking saga pohon seed dormancy. A completely randomed design was used in this experiment. The experiment consisted of 100 seeds and replicated 4 times. The result showed that the best pre treatment to break saga pohon seed dormancy was by soaking the seeds in sulfuric acid for 30 minutes. By using this treatment the germination percentage of saga pohon seeds was 92 %.
