【摘要】 1995～1997年在山西省临汾市就光照强度在小麦灌浆期对小麦不同品种结实率、千粒重的影响进行了研究。结果表明，在灌浆期光照强度减少1／2时，小麦的结实率、千粒重普遍下降，结实率平均减少19．3％，千粒重损失27．3％，不同品种间差异较大。更多还原

【Abstract】 During 1995～1997, a study on the relation between light intensity and rate of fructify,weight of 1000 grains of wheat were carried out. Result shows that when light intensity was reduced to1/2, these has been a decrease in rate of fructify and weight of 1000 grains of wheat. The rate of fructify and the weight of 1000 grains average reduce19. 3% and 27. 3%, respectively.更多还原
