The flowering and fruiting are much different between the trees of Scaphium lychnophorum which were introduced in Jinghong. The trees have on-year of fruiting once 3-4 years and off-year continue 2-3 years. In Jinghong, the low temperature in the early flowering period is one factor among the main factors effecting flowering and fruiting of trees. The trees which vegetative grow flush and which grow on the place in a poor sunlight are effected their flowering and fruiting, too.
