胖大海树开花结果习性观察

The Habit of Flowering and Fruiting of Scaphium lychnophorum

景洪引种的胖大海树,开花结果性状株间差异大,且多数植株隔3～4年才有一次结果年。开花前期的气温偏低是影响胖大海树开花结果的主要因素之一。植株营养生长过旺和光照不足等,也是影响因素。

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.
