摘要: 水稻不同品种的叶绿素(a+b)含量及叶绿素 a/b 比值是不同的。叶绿素(a+b)含量生育初期较少,然后逐渐增多,到生育后期则下降。水稻各品种由苗期至乳熟期叶绿素(a+b)含量的变异系数为12~20%,而叶绿素 a/b比值的变异系数只有4~8%。剑叶的叶绿素 a/b 比值最大,越是下位叶越低。叶绿素(a+b)含量与净光合速率呈显著的正相关,其相

Abstract: Experiments on rice were conducted for 4 ycars.Differences of chl-orophyll(a+b)content and a/b ratio among varieties were significantwhen grown under the same condition.The changes in chlorophyll(a+b)content and a/b ratio resulted from the changes in chlorophyll a and/orchlorophyll b.The chlorophyll
