The paper studied the contents of Chlorophyll and anthocyanin in the leaf of Chinese buckeye in spring.The results showed that the leaf area and the specific leaf weight increased rapidly with the prolongation of time.For example,the leaf area and the specific leaf weight in 12d were 8.659 and 1.57 times greater than that of 2d respectively.Simultaneous the contents of Chlorophyll increased and the contents of anthocyanin decreased.The ratio of Chlorophyll/anthocyanin was decreased rapidly. The ratio in 12d...
