控制小麦品种间粒重差异的生理因素尚未完全解决。本文所述的实验表明，两个小麦品种的最终粒重主要取决于干物质积累速率，而干物质积累速率又取决于形成的胚乳细胞数。胚乳中的细胞数似乎受开花后前2周内籽粒同化物供应的调节。
THE physiological factors controlling differences in grain weight between cultivars of wheat are not fully resolved. The experiments described here indicate that final grain weight in two cultivars of wheat is mainly dependent on the rate of accumulation of dry matter, which in turn is governed by the number of endosperm cells formed. Cell number in the endosperm seems to be regulated by the supply of assimilates available to the grain during the first 2 weeks after anthesis.
