摘要
工厂大气混合污染对常绿树叶片组织的影响如下:1.叶片角质层、栅栏组织、海绵组织变薄。2.茶花叶片栅栏组织、海绵组织增密,胞间隙缩小,维管束加多,旱性结构提高。3.广玉兰叶片保护组织、同化组织、维管束变形、坏死,叶片黄化枯萎。
The effects of factory mixed air pollution on structures of evergreen tree leaves are as follo(?)s: 1. The cuticular layer, palissade tissue and spengy tissue of the leaf became thinned. 2. The number of bundles added, the intercellular spaces lessened, the density of palissade tissue and spongy tissue of camellia japoniea leaf increased. This indicate that the xeromorphic structure of their leaves is strengthened. 3. The protective tissue assimilating tissue and bundle of Magnolia grandiflorne leaves deformed and there are mang necrotic cells in these tissuer and became yellow.
