| Abstract: | Paraffin sectioning method was employed to study the anatomical structure of the leaf of Platanus orientalis L.The result showed that the leaf of Platanus orientalis L.consists of epidermis, mesophill and veins,with its thickness to be142.4μm.The epidermal cells around the principal vein was small and closely arranged and its palisade tissues were distributed in the epidermis,its spongy tissues and veins well developed.There were densely distributed stomata on the surface of the leaf with a density of 31.63 per unit area,showing less drought resistant than Platanus occidentalis Linn. |
