Title: Photosynthetic and Chlorophyll Fluorescence Characteristics of Xantha Type Rice Mutant
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.
