Preliminary study on leaf blade structure and moisture characteristics of three kind of ornamental lily of tube seedlings

The leaf structure and moisture of three kinds of ornamental lily of tube seedlings were studied in this paper.The results showed that the leaf of all lily was such as leaf surface,the differentiation of upper and lower epidermis monolayer,palisade and spongy tissues were not obvious.The thickness of arteries and mesophyll organization of oriental lily was biggest among three kinds of ornamental lily,and that of the Asian lily was most small than other two kinds of ornamental lily.The stomata of leaf of ornamental lily were located at under epidermis,its guard cells presents like dumbbell-shaped.The stomata opening of longifloruml lily was the biggest and that of Asian lily was the smallest.The water content of three kinds of ornamental lily was high,the water potential and water content of Asian lily were the highest and that of longiforuml lily was the smallest.
