| 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GR_(max)和平均灌浆速率GR_(mean)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. |

| Keywords: | Longjing31 shading yield SPAD grain-filling |
