Abstract

Fruit drop potentially decreases the yield of durian, so it needs to be controlled. Its control canbe done better when information on pattern of fruit drop is available. This research examined fruit dropof different panicle positions of two durian varieties. Observed panicle positions i.e. bottom, central,and upper of a tree, observed varieties i.e. Kani, Monthong. Observed variables were percentage offlowery branch, number of flower panicle, total number of flowers, number of flowers per panicle, andfruit set. The objective of this research was to know the pattern of fruit drop and flowering of differentpanicle positions of two varieties of durian.
