[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 lily Lilium longiflorum Asian 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.
