Abstract

Kamagong (Diospyros blancoi  A. DC) is a commercially significant species that have been listed as critically endangered in the country due to unreported logging and overuse of this native trees. In this study, different levels of alpha naphthalene acetic acid were used to soaked the D. blancoi seeds and determine its germination. The study laid out in Complete Randomized Design (CRD) with four treatments (0 ml, 5 ml, 10 ml, and 15 ml) of levels of ANAA and replicated three (3) times. Each treatment comprises of 30 seeds with10 seeds per replication. Over a number of weeks of observation, germination percentage and germination rate were used as a parameter in determining germination. The study results a highly significant difference in treatment 2 (5 ml of ANAA) yielded the highest germination percent and mean germination rate with Pr (>F) values of 0.0131 and 0.0099 respectively. Hence, the study concluded that germination of D. blancoi seeds using ANAA produced a good result at the concentration levels of 5 ml. Furthermore, this concentration is recommended for seed germination of D. blancoi.
