源与库对作物产量都有限制作用,但是,在那一方面起到主导作用,有二种不同的看法。有的认为库比源有更大的效应,因为作物的收获产物是作物体的最大贮藏库;有的认为作物产品器官的多少和大小,主要决定于光合产物的供应量,因而源是形成产量的根本等说法不一。然而,由于各种作物形成产品器官的不同,品种间遗传特性的差別,作物生长发育阶段的不同,以及作物生活环境条件的不同,源或库对限制产量的重要性可能有所差 Both sources and stocks have a limited effect on crop yields, but there are two different perspectives on which side play a leading role. Some believe that the reservoir has a greater effect than the source because the harvested product of the crop is the largest repository of the crop and some believe that the amount and size of the crop product organ depends primarily on the supply of photosynthate and thus the source is the yield The fundamental argument is not the same. However, due to the differences in the organs of the crops, the genetic characteristics of the cultivars, the differences in crop growth and development, and the different environmental conditions of the crops, the importance of the source or sink to yield restriction may be poor
