低温处理对卷丹百合分瓣及生育期的影响

Effects of Low-temperature Treatment on the Tillering and Growth Stage of Lilium lancifolium Thunb.

[目的]研究不同低温处理对卷丹百合(Lilium lancifolium Thunb.)的影响。[方法]探讨2、5℃低温处理不同时间对卷丹百合分瓣数及生育期的影响。[结果]经不同低温处理后栽植,卷丹百合分瓣数与低温处理时间呈极显著正相关,且植株生育期长短与低温处理时间呈负相关。[结论]低温处理25 d以上(含25 d)能明显提早植株开花时间,且能缩短植株生育期。

[Objective] To research the effects of low-temperature treatment on Lilium lancifolium Thunb.[Method] Effects of 2 and 5 ℃treatments for different time periods on the bulbs and growth stage of L.lancifolium were researched.[ Result] After different low-temperature treatments, the tillering number of L.lancifolium showed extremely significant positive correlation with the time of low-temperature treatment. The growth period of plant showed negative correlation with the time of low temperature treatment.[ Conclusion] Low-temperature treatment for more than 25 d can significantly enhance the flowering time of plant, and can shorten the growth period of plant.
