Abstract: The leaf epidermal micro-morphology characteristics of wild Cerasus humilis(Bge.) Sok. including seeded and grafted types living in Yanshan Mountains were observed with Scanning electron microscope (SEM). The results showed that the upper and lower epidermal cells morphology can be divided into two types, one type was concave and connected like a honeycomb and the other type was ridgy and nearly circle. The upper epidermal cells were covered with striated cutin. There were some epidermal trichomes but no stomata on the upper epidermis, while on the lower epidermis only stomata distributed. The stomata extruded from epidermal cells which belong to irregular type. The average length, width, size and density of stomata were 8.22±1.30 μm, 2.55±0.65 μm, 21.64±8.60 μm2 and 836.23±197.16 mm-2, respectively. Stomata characteristics indicated significant differences in different plants and different epidermal cell morphology, which can be used as basis for seed-selection and research on anti-drought stress of wild C.humilis(Bge.) Sok.

Key words: Cerasus humilis(Bge.) Sok., leaf epidermis, stoma density, scanning electron microscope(SEM)
