grain-weight的意思|示意

The direct reasons which cause the yield rate are that the disease decreases the grain weight per panicle and increases the rate of diseased grains.

它对产量影响的直接原因是减少了单穗实粒重，增加了病粒率。

Therefore, it was very important to take effective measures to increase the early grain weight for gaining a high final grain weight.

在早期粒重高的年份，最终粒重常常也高，因此，在生产实践中，采取有效措施提高早期粒重对获得最终高粒重具有重要作用。

These mutants were almost accompanied by variations in agronomic traits such as dwarfism, high sterility, heading date or grain weight.

抗病突变体大多伴随着株高、熟期、育性或粒重等农艺性状的变异。

The hundred - grain weight increased with the increasing nitrogen content.

百粒重随着施氮量呈现递增趋势。

No correlations was between grain weight and grain filling.

充实度与粒重不相关。

The general genetic ability of the grain number per spike and the grain weight per spike reduced, but the narrow genetic of them increased.

穗粒数和单穗粒重的广义遗传力下降，狭义遗传力提高，但穗粒数的广义遗传力下降的幅度较大。
