摘 要 ：用简易的人工光氧化和遮荫条件对35个水稻种质进行筛选，鉴定出既耐光氧化又耐荫等4种品种类型，并用耐光氧化又耐荫的品种武育粳3号和对光氧化和遮荫均敏感的品种香粕进行光合特性测定.结果表明，以香粕为对照，在光氧化条件下，武育粳3号的PS Ⅱ光化学效率和光合酶Rubisco活性较稳定，C4光合酶PEP活性诱导增加，因而光合抑

Abstract:35 rice germplasms were identified and the tolerant type was found under photooxidation and shading conditions. The comparison of photosynthetic characteristic was made between the tolerant and sensitive varieties to both photooxidation and shading，wuyugeng and Xiangxian. The results showed that as
