Abstract: The relation between leaf structure and photosynthetic characters was studied in this paper with statistical methods, such as linear correlation, multiple regression based on five tea varieties. The results were shown as follows: Moderately positive correlation of the density of palisade cell, the ratio of the length to width of the first layer palisade cell, the width of palisade tissue, the ratio of the width of palisade to the one of spongy tissue to the accumulative amounts of photosyn that were significant or highly significant and the linear correlation coefficient(R) were 0.828(P<0.01), 0.652(P<0.01), 0.429(P<0.01) and 0.374(P<0.05) resspectively. The relation between the numbers of choroplast grana, the numbers of chloroplast lame lase structure and the accumulative amounts of photosynthate was also observed(r=0.475, P<0.01, r=0.330, P<0.05).
