Abstract:Leaf epidermal cells and stomatal apparatuses in 20 ginger cultivars were observed under light microscope and scanning electron microscope and leaf shape index was examined as well. The leaf epidermal cells are hexagonal, long hexagonal and irregular hexagonal in shape. Stomatal apparatuses are all paracytic with 21.5-31.0μm in width. The stomatal apparatus indices are from 1.75 to 8.22 and leaf shape indices vary greatly, which can be used in elucidating relationship among the cultivars.
