| Abstract: | 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. |
