茶树叶片表皮的角膜,是由一种角质的脂类化合物渗入到细胞壁中的变化,其厚薄往往与外界环境条件紧密相关。角化的细胞质仅能透光而不透水、透气,并且有保护叶肉组织抵抗外界不良环境的作用。这种角质膜是品种在系统发育过程所形成,其花纹因品种不同而异,是品种分类的依据之一,也是识别品种抗逆性强弱的重要特征。 一、生态环境与角质层:在一定的生态条件下,长期系统发育中,生态型与环境达到最大的统一。各种器官、形态结构、功能与环境也达到统一。茶树由生长在森林下潮湿多雾、漫射光多、水分散失少的环境中随着地形的变迁,大气的变化,自然和人为地各处传播,逐步离开了原来的环境,于是产生了种种生态适 The cornea of ​​the epidermis of tea leaves is a change in the penetration of a keratinous lipid compound into the cell wall, and its thickness is often closely related to the external environmental conditions. The keratinized cytoplasm is only translucent and impermeable, breathable, and protects the mesophyll from the adverse external environment. This kind of keratin is the formation of the species in the process of phylogenetic development. The patterns of the keratinocytes vary with the varieties, which is one of the basis for the classification of varieties. It is also an important feature to identify the strength and weakness of the varieties. First, the ecological environment and the stratum corneum: Under certain ecological conditions, the long-term system development, the largest ecological and environmental unity. A variety of organs, morphological structure, function and environment also reached unity. Tea tree grows in the forest under the damp and foggy, diffuse light, water loss less environment with the terrain changes, changes in the atmosphere, natural and man-made spread everywhere, and gradually left the original environment, resulting in a variety of ecological suitable
