每穗总粒数与结实一次枝梗数和现存二次枝梗数均密切相关。
Total grain number per spike correlated closely to fruiting primary rachis branch number and existing secondary rachis branch number.
这可能是由于播种期的推迟，每穗总粒数、每穗实粒数和有效穗显著降低。
The spikelets and the setting grains per panicle and effective panicle number per unit land area all decreased with the delay of seeding times.
随着品种演进产量逐步提高，其原因主要是每穗粒数的增多导致总颖花量的增加。
Increase in grain yield was attributed mainly to the increase in total number of spikelets, which resulted mainly from a large panicle.
