Abstract: Using Idesia polycarpa Maxim. No. 1 five-year fruiting tree as test material, for three tree shapes of spindle-shaped, naturally open-shaped and evacuated stratified, fruiting branches, branch analogy, single panicle weight, fruit yield and other main characters were compared. The results showed that, for the evacuated stratified tree shapes, the number of fruiting branches was the highest, branch analogy was the best, single panicle weight and yield were the highest.

Key words: Idesia polycarpa Maxim., tree shape, branch to branch analogy, weight per ear, production
