摘　　要：对东方百合种球冷藏处理(2℃)74天后进行135天的冻藏处理(-1℃),研究其冷藏打破种球休眠以及冻藏抑制种球萌发的适宜时间。从花茎长度、花苞的数量、花期及第1花苞的大小等4个指标综合评价。参试品种为'西伯利亚'、'元帅'、'索蚌',种球周径选12～14cm、14～16cm2种规格,适宜的低温处理天数分别为74～102天、72～87天,42～87天、74天,42～87天、42～87天。'元帅'周径为14～16cm的种球冷藏时间不宜少于42天,其他处理的冷藏时间均不宜低于29天。'索蚌'2种规格的种球,可将其低温贮藏时间延长至102～209天。This experiment was purposely to research the flowering characteristics of oriental lily bulbs stored at low-temperature（firstly cold storage at 2℃ for 74 days,then frozen storage at-1℃ for 135 days）.The analysis for flowering characteristics such as flower stem length,numbers of inflorescence,size of the first inflorescence and flowering duration was as followed：for ＇Siberia bulbs with perimeter 12-14 cm and 1416 cm, ＇Acapulco＇ bulbs with perimeter 12-14 cm and 14-16 cm, ＇Sorbonne＇ bulbs with perimete 12-14 cm and 14-16 cm,the suitable storage period was 74-102 days,72-87 days,42-87 days,74 days,42-87 days and 42-87 days respectively.For ＇Acapulco＇ bulbs with perimeter 14-16 cm,the shortest storage period was more than 42 days,and for the other kind of bulb,the shortest storage period was more than 29 days.Moreover, for both ＇Sorbonne＇ bulbs with perimeter 12-14 cm and 14-16 cm,the storage period could be delayed to 102-209 days.
