Diagnosis of tree architecture in young 'Fuji' apple

摘要

Based on analysis of architecture in trees at high planting density, the 'Fuji' tree architecture was classified into four types, i.e., the weak, the high-yielding in plain, the moderate -vigor, and the young with active growth. The target architecture for apple trees was moderate-vigor onr. Some functions to distinguish tree architecture were developed for use in classification of tree architecture.
