摘要
本文是大豆光合速率与产量关系研究的回顾，旨在促进大豆高光效育种的进展。研究指出，目前在大豆光合速率与产量关系研究中有三种研究结果：正相关、不呈相关关系和呈负相关关系。分析了影响大豆光合速率与产量呈负相关主要因素。认为这些影响因素导致在特定条件下，光合速率与产量呈不相关和负相关的假象。进一步阐明产量主要依赖于光合速率，但依赖的程度受体内的生理过程和环境因素的影响，致使光合速率与产量关系变得复杂化。阐明了高光效育种的目标，讨论了光合速率与产量无关、甚至呈负相关的某些因素。
This paper is a review about relationship between soybean photosynthetic rate (PR) and yield. The objective is to promote the progress on high PR breeding of soybean. It indicated that there were either positive or negative or even no relationship between them. It also showed that factors under special conditions affected and caused the false phenomena with no or negative interrelationship. It further indicated that yield mainly depended on PR but the extent was affected by physiological metabolization and enviromental factors. The interaction of such factors made the relationship complicated. The author clarified the targets of the high PR breeding and disagreed the opinion that were no of negative interrelation between photosynthesis and yield.
