Observations on the Microstructure of Leaf Surfaces of Wild and Cultivated Olive with SEM

The leaf surface of wild and cultivated olive were observered with scanning electron microscope (SEM 505). It showed that there are many differences between them in microstructure. It was mainly that the lepidotes on the midrib of the lower surface of the leaf of the wild olive are rare,while those of the cultivated olive are densly covered. And,on the lateral sides of the guard cells of the wild olive,there are many coarse striae,while those are few on the cultivated olive.
