Abstract: Taking Distylium buxifolium named "Li mei" as the research object, selecting the randomly selected 200 strains of the same plant, the trend of plastid pigment content change and dynamic change were studied in the spring by measuring the leaf length, leaf width, stem length, and leaf area index. The results showed that there was a growth trend in the leaf plastid pigment content, leaf area, RGB value, leaf length, leaf width and branch length, et al. The extent increased obviously about varieties "li mei" chlorophyll a and chlorophyll b growth than the carotenoid content, the chlorophyll a and chlorophyll b content growth speed were slow in Apri1 1, but the growth rate were sharply higher from April 7;The growth rate of leaf area varieties of li mei's were the fastest on March 28 to April 1 day, the peak was the largest in April 7. Form April 7, as the blade gradually matured, leaves began to lost water and atrophy, the growth of leaf area was no longer obvious; The variation trend of the variegated leaf color was decreased in red and blue, and the green component increased. It showed that the leaf color of D. buxifolium named "Li mei" was changed from purple to green in spring. Branchlets grew slowly from March 15 to April 12, and grew faster after April 12. The pigment content of leaf plasmid and the dynamic value of the leaves of D. buxifolium named "li mei" rose the fastest between March 28 and April 7.

Key words: Distylium buxifolium, pigment content of leaves, leaves dynamic, spring
