摘    要:生物良种的选择,历来是人类最关心的事,本文讨论的是植物的选种方法,我们在品质基本相同的几个品种中选择最优品种.这里最优品种指的就是产量最高者.植物的产量是由光合作用所产生的生物量,所以,光合性能强的物种常为最优品种.本文所介绍的选种方法,就是根据不同品种的光合性能的强弱来研究品种的优劣,而植物光合性能强弱可以通过植物的光合总量来确定.本文计算了三个猕猴桃品种的光合总量,其中光合总量最高者为最优品种(产量最高),这与生产实践完全一致,所以光合性能选种法得到了生产实践的验证.

关 键 词:中华猕猴桃  净光合速率函数  净光合总量

Abstract:Well-bred selection is one of the most important aspects that breeders considere during the breeding. In this paper, the method is given for selection to get the optimal kind, which could get the highest yield, among some similar ones. The yield means the plant biomass produced by photosynthesis, higher yield indicates higher photosynthetic capacity. Based on the power of the photosynthetic capacity, plant photosynthetic yield are mensurated and the selecting method is given. Photosynthetic yield of three kinds of Actindia Chinese Planch indicates that the kind with the highest photosynthetic capacity is the optimal kind, which is accorded with the breeding fact. It is showed selecting by photosynthetic capacity is one of powerful methods for selecting breeding.
Keywords:Actinidia Chinesis Planch  Function of net photosynthetic  Total amount of net photosynthesis
