Bearing Habits of Acer truncatum and the Relationship Between Its Branch Characteristics and Fruiting Performance

In recent years, seeds of the Shantung maple have attracted attention for their economic and medicinal value due to high nervonic acid content in seed oil, which has a curative effect on some demyelinating diseases. However, few studies investigated its fruiting habits branch characteristics; therefore, purpose this research was investigate fruit bearing A. truncatum analyze relationship between characteristics performance provide basis management. The structure, flower-bearing position, continuous ability 200 individuals were recorded from 2014–2017. results showed that parent shoots usually short (less than 10 cm) with developed by terminal mixed buds shoot. can form Y-shaped group many years via lateral shoot position slenderness had significant influence yield weight, length, thickness. top basal diameters Group comparison most effective convenient method selection based diameter shoots, among thicker 3.08 mm bud vegetative greater yield, number fruit, weight.
