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、花期及第一花苞的大小等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12~14 cm、14~16 cm两种规格，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14~16 cm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。

Abstract:

This experiment was purposely to research the flowering characteristics of oriental lily bulbs stored at low-temperature (firstly cold storage at 2℃for 74 day, 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 perimeter12-14 cm and 14-16 cm, ‘Acapulco’ bulbs with perimeter12-14 cm and 14-16 cm, ‘Sorbonne’ bulbs with perimete12-14 cm and 14-16 cm, the suitable storage period was 74-102 days, 72-87days, 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.
