【Abstract】 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.
