【摘要】 以中国产亚洲百合鳞茎为试材 ,探讨了2℃ ,7℃ ,12℃条件下的低温处理效应。结果表明 :处理温度越高 ,基生根出现腐烂症状越早。不同品种之间的耐贮性差别较大 ,Cordelia属于耐贮藏品种。鳞茎发芽所需时间与低温贮藏时间有显著负相关性。不同品种对低温的反应不同 :Elite和Protao经7℃处理生育期最短 ,而Pollyana和Cordelia经2℃处理生育期最短。在同一温度下 ,随着处理时间的延长 ,生育期缩短。鳞茎冷温处理不足 ,导致植株采收整齐度差 ,甚至不能出苗。更多还原

【Abstract】 The effectiveness of treatments with lower tempexature(2℃,7℃,12℃)were tested in the Asiatic lily bulbs harvested in Chiˉna.The results indicate that the higher temperature the lily bulbs treated,the earlier roots rotten.Cordelia is resistant to higher temˉperature.There is significant negative correlation between sprouting time of bulb and treated days.The reactions to low temperature are different among various hybrids.Elite or Protao placed at7℃and Pollyana or Cordelia placed at2℃have the shortest growth period.Prolonging the days of storage,the growth period is shorten.The insufficient cold treatment result that the regularity of harˉvesting is poor,even the plant can’t emerge.更多还原
