The results indicated that the chloropyll and carotenoid content and the protein content and the SOD and CAT activities decreased and POD activity increased after the appearing zebra\|leaf character. However, it was found that every index was reversible in the process of recovery of the yellow part of the leaves into green. It was suggested that the expression of zebra\|leaf character might be due to abnormal chlorophyll metabolism. It was related to the content of pigment and the enzyme activities of POD, CAT, and SOD. 水稻 色素突变体 “斑马叶”性状 叶绿素 酶活 10.14188/j.1671-8836.2000.06.026 Q945 国家“九五”科技攻关项目!（ 960 2 0 0 2 0 2 ） 2000-06-01 2021-04-01 6
