【摘要】 对东方百合种球冷藏处理(2℃)74d后进行1 35d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,‘西伯利亚’周径为12～14cm、14～16cm的种球,‘元帅’周径为12～14cm、14～16cm的种球,‘索蚌’周径为12～14cm、14～16cm的种球,适宜的低温处理天数分别为42～102d,42～87d,74～87d,74d,74～87d,74～87d。‘元帅’周径为14～16cm的种球冷藏时间不宜少于42d,其它处理的冷藏时间均不宜低于29d。‘索蚌’两种规格的种球,可将其低温贮藏时间延长至102～209d。更多还原

【Abstract】 This experiment was purposely to research the flowering characteristics of Oriental Lily with the bulbs stored at low-temperature(firstly cold storage at 2℃for 74 day,then frozen storage at -1℃for 135 days).The characteristics such as flower stem length,numbers of inflorescence,size of the first inflorescence and flowering duration were analysed,the resultes showed as followed:For ’Siberia’ bulbs with perimeter 12～14cm and 14～16cm,’Acapulco’ bulbs with perimeter 12～14cm and 14～16cm,’Sorbonne’ bulbs with perimete12～14cm and 14～16cm, the suitable storage period respectively was 42～87 days,42～102 days,74～87 days,74 days,74～87 days and 74～87 days.For ’Acapulco’ bulbs with perimete14～16cm,the shortest storage period was more than 42 days,and for the other size of bulbs,the shortest storage period was more than 29 days.Moreover,for ’Sorbonne’ bulbs with perimeter 12～14cm and 14～16cm,the storage period could be delayed to 102～209 days.更多还原
