[Objective] The study was to compare the structural and moisture characteristics of leaf from the plantlets of three types of ornamental lily(Lilium brownii).[Method] The paraffin sections of leaves of tested lily varieties were prepared and then observed under microscope,and the stomatal characteristics and moisture characteristics of tested lily varieties were measured.[Result] All the three ornamental lily varieties show isobilateral leaf,single layer of epicuticula and lower epidermis,and no obvious differentiation of palisade tissue and spongy tissue;their stomata distribute in lower epidermis,and the guard cells are dumbbell-shaped;all of these materials present high moisture.For the leaf sickness,midrib sickness and mesophyll tissue sickness,the order was determined to be oriental lilyLilium longiflorumAsian lily;of the three types of ornamental lily,Lilium longiflorum has the largest stomatal aperture and Asian lily has the smallest;focusing the water potential and moisture,the turn was Asian lily oriental lily Lilium longiflorum.[Conclusion] The study may facilitate the artificial regulation of the growth conditions of the plantlets of ornamental lily.
