摘　　要：为研究低温条件对空气凤梨生长特征的影响,将5个空气凤梨品种置于不同低温条件下进行处理,测试其耐低温情况。结果表明,在人工控制的恒定低温条件下,空气凤梨可以耐受0℃低温。短期0℃低温(10 d内)会对植物产生轻微冻害,但低温去除后可以恢复正常生长。在自然低温条件下,空气凤梨可以耐受短期(10 d左右)-5℃～0℃的低温,低温条件去除后,可以恢复且对生长有利。但如果超过20 d,低温条件去除后,很难恢复。各品种对低温耐受性强弱的顺序依次为:松萝>阿拉杰>锥头铁兰>富奇思>维路提那。in order to research the effect of low temperature on the growth of airplants （Tillandsia）, five species of airplants were treated under low temperature. The results showed that the airplants can endure 0℃ low temperature treatment, which can restore after low temperature removal, although the airplants suffer a little harm. In natural low-temperature condition, the airplants can tolerate low temperature of --5℃--0℃ for 10 days, which can restore after low temperature removal. Moreover, the low temperature is good for the airplants growth. But the plants can not restore if low temperature lasts over 20 days. The tolerance ability for low temperature is T. usneoides 〉 T. araujei 〉 T.ionantha conehead 〉 Z fuchsii〉 T. velutina.
