Changes of Amount and Morphology on Starch Granule in Scales of Lilium Davidii Var. Unicolor During Bulb Development

摘要：

Changes of starch granules in the middle scales of Lilium davidii var. unicolor bulb weighing about 29.2 g were studied with the scan electron microscope (SEM). Larger long elliptical granules without crackles are observed gathering and stuffing in the cell at planting stage. From plantlet to budding, the larger and smaller granules present together and the total amount decrease; meanwhile, the vertical axis of the larger one becomes shorter gradually, and the smaller one increases in size. From bud veraison to withered stage, the amount of starch granules increases significantly. Furthermore, the size difference between two types granules disappears gradually and assumes the shape a rough ellipse. The amount of starch granules reaches the maximum at the withered stage, and at all the growth duration, it is a little lower in the cells between the bigger and smaller vascular bundles than which in the cells beside the bigger ones.
