以Y两优1号为材料,探讨了收割后不同测定时间对水稻结实率的影响。结果表明:随测定时间的后推,结实率呈下降趋势,这种趋势是由秕谷率的变化引起的,与空壳率无关。
Taking Y Liangyou 1 as material, the effects of different measuring time after harvest on the seed setting rate of rice were discussed. The results showed that the seed setting rate decreased with the postponement of measurement time. This trend was caused by the change of the trough rate, which was not related to the shell percentage.
