树木叶片解剖结构由表皮、叶肉、维管束组织组成。不同树木的叶片表皮、叶肉等结构是有差异的。不同解剖结构的叶片生理功能不同,抗性强、弱亦有差异。因此,对生长在硫污染区,氟污染区,氟硫复合污染区的树木从叶片受害的表征,将其分为抗性弱、抗性中、抗性强的三种类型进行解剖观察。本文仅从叶片的表皮、叶肉组织进行比较,测定树木对大气污染质的抗性。为污染区选择抗性强的树种提供依据。
Tree leaves anatomical structure by the epidermis, mesophyll, vascular bundle organization. Different tree leaves epidermis, mesophyll and other structures are different. Different anatomical structure of the leaves of different physiological functions, resistance, weak also have differences. Therefore, the tree growing in sulfur-contaminated area, fluorine-contaminated area and fluorine-sulfur compound contaminated area was characterized by the damage of the leaves and classified into three types, which are weak resistance, moderate resistance and strong resistance. This article only from the leaf epidermis, mesophyll tissue comparison, determination of trees on the air pollution resistance. Provide a basis for selecting resistant tree species in polluted area.
