摘要
通过研究不同程度小麦叶枯性病害对灌浆过程的影响发现 :重病植株干物质积累时间短 ,干物质量低 ,营养物质转移时间短 ,造成子粒不饱满 ,穗重下降。病害对小麦穗部的影响使子粒中各种氨基酸及粗蛋白含量有不同程度的下降 ,导致品质变化。
The effect of different wheat leaf blight conditions on the grain filling rate was studied, the result showed: the higher severity the disease was ,the shorter the accumulation of dry matter was .So the yield was decreased. The occurance of this disease can also affect the quality of wheat, this disease can make the content of different animo acid and crude protein decreased.
