采用叶片徒手切片和氯锌碘分化染色，观测了10个茶树品种叶片角质层。角质层的厚薄与叶面积大小有关，叶面积大的品种一般角质层较薄。叶面光泽性强弱与角质层沉积蜡质多少有关，光泽性强的品种蜡沉积的多。不同品种叶片溶液残留量明显不同，这主要与该品种叶片着生角度，叶面隆起性和光泽性强弱等叶片形态有关。叶片上斜着生、叶面不隆起、光泽性强的品种，溶液残留量少。叶面光泽性强弱对溶液渗入叶内的量也有影响，光泽性强的品种渗入量少。同一叶片不同部位溶液残留量不同，叶尖部、损伤部位和低凹处等溶液残留量和渗入叶片内的量多于同一叶片的其他部位。 Leaf stratum corneum was observed by using free leaf sections and zinc, zinc and iodine staining. The thickness of the cuticle is related to the size of the leaf area. The larger the leaf area is, the thinner is the cuticle. Foliar follicular strength and the amount of wax deposition of the stratum corneum, waxy varieties of wax deposition and more. Residues of different varieties of leaves were significantly different, mainly with the breed angle of the variety of leaves, leaf surface uplift and glossiness of the blade morphology. Staggered on the leaves, leaf surface is not uplift, shiny varieties, less residual solution. The foliar gloss strength of the solution into the leaves also affect the amount of the amount of strong gloss varieties infiltration less. Residues in different parts of the same leaf were different, and the amount of solution remaining in the tip, lesion and depression and the amount infiltrated into the leaf were more than those in other parts of the same leaf.
