不同超高产杂交稻生育后期光合性能的比较

Comparison of Photosynthesis Performance at Late Growth Period among Super-high Yield Hybrid Rice

在大田条件下,以几种超高产杂交稻为材料,对其抽穗后功能叶面积、叶片着生角度、叶绿素、光合速率等进行研究。结果表明,C两优87的光合性能较好,具有较大的光合叶面积、叶比重,叶片着生角度最小,生育后期叶绿素含量高,且下降较慢,光合速率高。

Under field conditions, the photosynthetic characteristics at late growth stage among different types of super-high yield hybrid rice varieties and the function leaf area, the SLW （the specific leaf weight）, effects of chlorophyll content, transpiration rate and photosynthetic rate on the yield were studied in this paper. The result showed that, C Liangyou 87 was ideal in the photosynthetic characteristics, with higher levels of function leaf area, SLW, chlorophyll content and higher photosynthetic rate.
