影响温州蜜柑产量的因素很多,除环境条件外,树冠本身各性状与产量关系也很密切,因此研究树冠性状与产量的关系,对制订高产栽培措施有着十分重要的意义。 通径分析在动植物育种和遗传研究中已得到了广泛应用。近几年来在作物生理及栽培中也开始应用这一方法,但柑桔树冠性状与产量的通径分析未见报导。本文以温州蜜柑单株叶面积、叶平面密度、树冠体积、分枝级数、末级分枝五个性状与产量相关和通径分析结果,来探讨影响柑桔产量的主要因素以及这些因素对产量的直接和间接作用,试图对温州蜜柑整形修剪提供依据。
There are many factors that affect the yield of Satsuma matsutake. Except for the environmental conditions, the relationship between the traits of the crown and its yield is also very close. Therefore, it is of great significance to study the relationship between crown traits and yield. Path analysis has been widely used in animal and plant breeding and genetic research. In recent years, this method has also been applied in crop physiology and cultivation. However, the path analysis of crown traits and yield of citrus has not been reported. In this paper, the main factors affecting the yield of citrus were studied in terms of the leaf area per plant, the leaf plane density, the volume of crown, the number of branching stages, the five traits of final branching, and the path analysis. The direct and indirect effects of yield, trying to provide the basis for shaping mandarin orange pruning.
