Traits of physiological genetics related to photoinhibition of photosynthesis in rice

【摘要】： <正> To elucidate genetic background of photoinhibitionof photosynthesis(PS),we studied the changes ofD_1-protein content and SOD activities in japonica andindica varieties, and their reciprocal hybrids afterphotoinhibition-inducing treatment by using isotopetracer.Judging from rate of photoinhibition (RPI) ofPS, we found that japonica varieties were more tol-erant to. photoinhibition than indica varieties.
