The photosynthetic basis for increasing the yield of major field crops is examined in terms of improving the interception of seasonal solar radiation by crop foliage, the efficiency of conversion of intercepted light to photosynthetic assimilates, and the partitioning of photoassimilates to organs of economic interest. It is concluded that, in practice, genetic and chemical manipulation of light interception over the season and of partitioning offer the most potential for achieving further increases in yield. During the history of improvement of genetic yield potential of crops, increase in the partitioning of photoassimilates to harvested organs has been of primary importance.
从提高作物叶片对季节性太阳辐射的截获量、截获光转化为光合同化物的效率以及光合同化物向经济价值器官的分配等方面，研究了提高主要大田作物产量的光合基础。得出的结论是，实际上，对整个生长季光截获和分配进行遗传和化学调控，在实现产量进一步提高方面最具潜力。在作物遗传产量潜力提高的历史进程中，光合同化物向收获器官的分配增加一直至关重要。
