ABSTRACT. The pruning waste of Java apple (Syzygium samarangense) tree branch can be used for its propagation by stem cuttings. The rooting process can be accelerated with the help of growth regulators, one of which is betung bamboo shoot extract. Using a randomized block design, this experiment aims at examining the effect of betung bamboo shoot extract with concentrations of 0%, 10%, 20%, 30%, 40% and 50% on the growth of Java apple stem cuttings. The samples were 48 stem cuttings with a diameter of 1 cm and a length of 15 cm. The results showed that betung bamboo extracts could accelerate the propagation process. The optimum concentration was 50%.
