Comparative Anatomy of Leaf Development among Four Fruit Vegetables
The study of comparative anatomy was conducted on leaves of tomato,eggplant, pepper and cucumber at different developmental stages. The results showed that the stomatal index increased before it, reached the highest value and then decreased gradually and stabilized during leaf development. There was a certain correlation between the blade aspect ratio of leaves and leaf shape. However there was no significant correlation on the blade aspect ratio between the leaves and the epidermal cells. The order of leaf differentiation was epidermis, mesophyll, veins in sequence. The epidermal cells was small and dense; their arrangement was regular and neat before the leaf unfolding. The epidermal cells began lateral and radial growth along with the development. And the leaf epidermal cell radial growth rate was faster than that of the lateral growth rate in tomato, eggplant, pepper. While there was no significant difference between the lateral and radial growth rate of leaf epidermal cells of cucumber.
