摘    要:对水稻黄化自然突变体(安农标810S)及其野生型(安农810S)的叶绿素含量、光合速率、叶绿素荧光动力学参数及单株产量进行了比较分析,结果显示:突变体在整个生长发育阶段总叶绿素含量均显著低于野生型,但突变体与野生型各自所配的杂交F1代叶绿素含量没有差异;从叶绿素a/b的比值来看,突变体的比值明显大于野生型;从净光合速率来看,无论是在1 d中的不同时间段,还是在不同发育时期,突变体均高于野生型;在不同发育时期和1 d中的不同时间段,突变体的FV/Fm、FV′/Fm′、φPS2、ETR2及QP均大于野生型,突变体的QN低于野生型;突变体自交繁殖的单株产量高于野生型,且从各自所配的杂交后代F1来看,突变体有较强的配合力。

关 键 词:水稻  黄化突变体  光合作用  叶绿素荧光

Abstract:The chlorophyll content,photosynthetic rate,chlorophyll fluorescence kinetic parameters and single plant yield of a new xantha type rice mutant(Annongbiao 810S) and its wild type(Annong 810S) were comparatively studied.It was showed that: the total chlorophyll content in mutant was significantly lower than that of the wild type at the whole growth stage,the chlorophyll content in combination F1 from mutant had no difference with that in combination F1 from wild rice;the Chl a/Ch b ratio in mutant was higher than that of wild type;the net photosynthetic rate of the mutant at different stages was higher than that in the wild type;the FV/Fm,FV′/Fm′,φPS2,ETR2 and QP in the mutant were higher than that in the wild type,the QN was lower in the mutant;the yield of self-breed in the mutant was higher than that of the wild type,the test of F1 hybrid performance showed that the mutant had excellent combining ability.
Keywords:Rice  Xantha mutant  Photosynthesis  Chlorophyll fluorescence
