Comparison of leaf structure of Bermuda grass grown under two habitats

Through observing the leaf cross sections of five varieties of Bermuda grass grown in rural area soil and vegetation concrete,the thickness of leaves,upper epidermis and lower epidermis,the diameters of vascular bundle(rosette structure)in the main vein of Bermuda grass were compared.The results showed:Except for Nanjing bermudagrass,the thickness of leaves of the other four varieties(Common hulled,Jackpot,040459/680 and Xinnong No.1)grown in vegetation were bigger than those grown in rural area soil;Except for 040459/680 bermudagrass,the thickness of leaf upper epidermis and lower epidermis of the other four varieties grown in vegetation were bigger than those grown in rural area soil;The diameters of vascular bundle(rosette structure)in the main vein of five varieties grown under the two habitats varied differently.
