摘　　要：综述了超高产水稻的光合特性、光抑制、光合性状的遗传规律和高光效材料的筛选等内容,比较详细地介绍了光抑制部位及其表现,光抑制的原因以及光抑制中热耗散的可能途径及作用等。由于叶黄素循环在水稻耐光抑制、增加热耗散中起着十分重要的作用,也总结了叶黄素循环的功能。最后,讨论和展望了超高产水稻的高光效育种前景。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.
