| Abstract: | The photosynthetic characters of super-high-yield rice(Oryza Sativa), its photoinhibition and genetic law of photosynthetic traits and screening of high photosynthetic efficiency materials etc. were reviewed in this paper. Especially, the locus of photoinhibition and its expression, its causes, possible manners and functions of thermal dissipation in photoinhibition were introduced in detail. Because xanthophyll cycle has very important functions in restraining photoinhibition and advancing thermal dissipation, the functions of xanthophyll cycle were summarized in the paper Finally, the outlook of high photosynthetic efficiency breeding in rice was discussed. |
