Abstract: The leaf epidermis submicroscopic structures of five varieties of Cynodon dactylon and wild bermudagrass planted in rural area soil and vegetation concrete were observed under scanning electron microscope (SEM). The shape, size and density of stomata on the leaf epidermis, epidermal appendages (mastoids, bristles etc.) of C. dactylon grown under the two habitats were compared. The five varieties and wild C. dactylon used in the experiments showed morphological responses to saline stress, and mastoids on upper and low epidermis increased, compared with control. On the epidermis of some varieties, such as Sahara, Hawk, and wild type, the mastoids around stomata distributed regularly, resulting in stomatal apparatuses below the cells around them. As the stomatal resistance increased, transpiration rate might decrease, and water usage efficiency might increase. Compared with control, increased stomatal density on upper and lower epidermis occurred on Kashi, Sahara, Heaven, and Hawk. According to the stomatal characteristics of the varieties grown on vegetation concrete, high stomatal density occurred on Kashi and Sahara. In general, among the five varieties of C. dactylon and wild bermudagrass used in this study, Sahara, Hawk, and Kashi showed better adaptation to vegetation concrete.
