摘要:
对水稻龙粳31抽穗后进行遮光处理，研究遮荫处理与未遮荫处理（CK）在产量及其构成、功能叶片的SPAD值和灌浆特性等方面的差异。结果表明：龙粳31抽穗后进行遮荫，主要影响千粒重和结实率两个产量因素，产量降低达到极显著水平；胁迫功能叶片SPAD值升高；遮光处理的强、弱势粒籽粒最大灌浆速率GRmax和平均灌浆速率GRmean均低于对照。
Abstract:
Shading on Longjing31 after heading,the differences of the yield and its composition,function leaf SPAD values and grainfilling characteristics between shading treatment and non-shading treatment were studied.The results showed that shading Longjing31 after heading affected the 1 000-grains weight and setting rate,and had the significant difference for the yield ; forcing function leaf SPAD values raised; the max grain-filling rate and the mean grainfilling rate of superior grains and inferior grains under shading treatment was lower than CK.
