为研究茶树叶片着生角度与叶部性状的关系，采用常规方法对５个品种（系）的７个叶部性状进行测定，并进行统计分析．结果表明：决定叶角的主导因子是叶厚，偏相关系数为－０．６００，达极显著水平，叶宽和叶厚对叶角的直接通径系数分别为０．９００和－０．７４０．叶位对叶片性状的影响大多成双曲线关系．高光效育种应挑选叶片较窄、叶肉较厚实的茶树作为育种材料
In order to study the relationship between the angle of emergence and the leaf traits of tea leaves, seven leaf traits of five cultivars (lines) were determined by routine methods and analyzed statistically. The results showed that the dominant factor determining the leaf angle was leaf thickness, the partial correlation coefficient was -0.600, reached the extremely significant level. The direct path coefficients of leaf width and leaf thickness to leaf angle were 0.900 and -0.740 . Leaf position on leaf traits mostly hyperbolic relationship. High light efficiency breeding should be selected leaves narrow, thicker leafy tea as a breeding material
