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Ｒｕ－ｂｉｓｃｏ含量和活性在转绿３０ｄ后超过亲本，光合速率在转绿１８ｄ后接近亲本。
A greenable albino mutant line of rice W25 and its original line 2177S were used as tested materials. The resultshowed that lower chlorophyll and protein content were found in leaves of W25 at the albino stage. The content of chlorophyllin leaves increased and got the same level as that of its parent line at the 30th day during the greening period. The content ofprotein and Rubisco also significantly increased, Rubisco content and activity were higher than those of parent line at the 30thday during greening period, the photosynthetic rate was close to that of parent line at the 18th day during greening period.
