Abstract: A greenable albino mutant line of rice W25 and its original line 2177S were used as tested materials. The result showed that lower chlorophyll and protein content were found in leaves of W25 at the albino stage. The content of chlorophyll in leaves increased and got the same level as that of its parent line at the 30th day during the greening period. The content of protein and Rubisco also significantly increased, Rubisco content and activity were higher than those of parent line at the 30th day during greening period, the photosynthetic rate was close to that of parent line at the 18th day during greening period.

Key words: greenable albino mutant line , chlorophyll, protein, Rubisco, photosynthesis

摘要： 对水稻转绿型白化突变系W25和亲本2177S进行了研究。白化期叶绿素和蛋白质含量很低，随叶片转绿，叶绿素含量增加，转绿第30天达到亲本的水平。在转绿过程中，蛋白质含量和Rubisco含量也显著提高。突变系W25叶片内的Rubisco含量和活性在转绿30 d后超过亲本，光合速率在转绿18 d后接近亲本。
