thousand seed weight的意思|示意

The results indicated that the grain per spike, seed setting rate, spikes per unit area and thousand grain weight had great contribution to the yield, especially grain per spike and seed setting rate.

结果表明：每穗粒数、结实率、单位面积穗数与千粒重对优质稻产量形成贡献较大，尤其是每穗粒数、结实率；

Output can be improved by reducing the plant height, improving available spikelet and seed setting rate and combining kernel number per spike with thousand kernel weight.

适当降低株高、增加有效小穗数、提高结实率、穗粒数与千粒质量并重、主攻穗粒质量是提高小麦产量的有效途径。
