椪柑早期结果与树相特征相关性的线性分析

THE LINEAR ANALYSIS OF CORRELATION BETWEEN EARLY FRUIT AND THE CHARACTERS OF PLANT SHAPE OF PONKAN

柑的早果性、丰产性与其树形结构有密切的联系。本文通过对瑞金、新干等产区实地调查，取得丰富的数据，对碰柑树冠生长量、夏梢生长量、高宽比、分枝数及裙枝数等多项因子与柑早期产量的相关性进行通径分析，揭示其线性关系，得出柑早结丰产的形成与其早期多项生产指标本质的内在联系。

There is a close relation between the early fruitage and productivity of Ponkan。and it'splant structure and shape.Through investigation in Ruijin County,Xingan County,etc,Jiangxi Province,the analysis on the correlation between the factors such as the increment ofcrown,the increment of summer tenders,the ratio of height to width,the number of branch-es,the number of assistant branches,etc,and the early yield of Ponkan was carried out bymeans of path analysis;It indicated the inner relation between the formation of early fruit andproductivity and the early indicators of growth of Ponkan.
