干旱对水稻抽穗后旗叶衰老和产量构成因子的影响
0
()
摘要:
研究干旱逆境对水稻抽穗后叶片衰老和产量的影响。结果表明,干旱导致水稻抽穗后旗叶绿色叶面积和叶绿素含量下降,相对电导率上升比水田水稻快,叶片易早衰;旗叶光合速率降低,谷粒增重缓慢,千粒重低,产量下降。

Effects of Drought on Senescence of Flag Leaf and Yield Factors in Rice
()
Abstract:
The effects of drought stress on leaf senescence after heading and yield were investigated.The result showed that drought could cause the decrease of area of flag leaf and content of chlorophyll,the increase of relative conductivity rate,premature senescence of leaf,the decrease of photosynthetic rate in flag leaf and yield.
Key words:  rice,drought,leaf senescence
