Abstract

Abstract: Microstructure and quantity of starch grains in the cell of Lilium formolongi‘Raizan’were studied with paraffin sections and scanning electron microscope（SEM）during low temperature storage and flower bud differentiation. The results indicated that abundant starch grains were stored in parenchyma cell of middle scales when bulb harvested. The starch grains declined significantly during low temperature storage but tended to increase when the flower bud differentiation. The starch grains were oval or long-oval，with distinct annular striation and attached with translucent membrane.

Key words: Lilium formolongi, scale, starch grain, microscopic observation
