[目的]探讨不同类型东方百合鳞茎低温冷藏过程中形态和生理变化的差异，为东方百合鳞茎采后休眠机理研究提供理论基础。[方法]以3个品种东方百合“索蚌”、“西伯利亚”、“木门”的鳞茎为试材，研究在低温冷藏过程中，鳞茎顶芽伸长、鳞片中淀粉含量和可溶性糖含量的变化。[结果]在2℃低温8周的冷藏期内，3个品种淀粉含量均呈下降趋势，品种间差异不显著。在处理的前3周“索蚌”可溶性糖含量急剧上升，“木门”在第2~4周时可溶性糖上升最快，在第8周时3个品种可溶性糖含量达到最高值。相同温度下，不同品种的东方百合芽萌发所需要的时间不一样，其中木门＞索邦＞西伯利亚。[结论]百合鳞茎解除休眠机理非常复杂，是多种生理因素共同作用的结果。

The differences between morphological and physiological changes in low temperature storage of Oriental Lilium Bulb varieties were discussed. The theoretical of postharvest dormancy mechanism would provide theoretical basis for bulbs. [Method] Bud elongating, starch contents and total soluble sugar contents were performed to investigate the effect of low temperature storage on three varieties“Sorbonne”,“Siberia”and“Conca D”. [Result] Bulbs were stored in moist peat moss for 8 weeks at 2℃. Starch contents of three varieties decreased continuously, but no significant difference was observeds. The contents of total soluble sugar increased significantly from 0 to 3 weeks for“Sorbonne”, From 2 to 4 weeks for“Conca D”, a peak value of three varieties appeared in the 8th week. The times of germination were different, and the fastest level was in“Siberia”, next came“Sorbonne”and“Conca D”. [Conclusion] Lily bulbs dormancy mechanism was very complex, which was the interaction of physiological factors.
