籽粒灌浆过程气候因子对不同品质类型春小麦产量和蛋白质含量的影响之三:光照的影响

Influence of Climate Factors During Grain Filling Process on Yield and Protein Content in Different Types of Grain Quality of Spring Wheat Ⅲ .The Influence of Light Intensity

在籽粒灌浆过程中对3个不同品质类型的春小麦品种进行遮光处理。结果表明,3个品种产量均随灌浆期光照度增大而增加,而蛋白质含量则随光照增大而下降,原因是产量的提高稀释了蛋白质含量。

Three spring wheat varieties in different types of grain quality were treated with the light interception during grain filling process. The results showed that the grain yields of all three varieties increased as the light intensity strengthened, while the grain protein contents of all three varieties decreased with strengthening of the light intensity. The grain protein content was diluted by reason of the increased grain yield.
