摘　　要：探讨了不同低温处理：4、8、12℃对新铁炮百合‘雷山’（Lilium formolongi‘Raizan’）鳞茎萌芽及花期的影响。结果表明：低温冷藏期间,处理温度越高,顶芽在鳞茎内萌动越早,顶芽和新根的生长速度越快。经不同低温处理后栽植,百合鳞茎发芽所需时间和植株生育期长短分别与低温处理时间呈显著负相关关系,随着处理温度的升高和处理时间的延长,鳞茎发芽快且整齐,株高、茎粗、花期的一致性好。低温处理时间不足,会导致百合鳞茎发芽和植株生长不整齐,甚至栽植当年不能出苗,从而延长生育周期。在4~12℃条件下,解除‘雷山’鳞茎休眠的合适低温处理时间是5周。This paper studied bulbs of Lilium formolongi cv.Raizan which stored at 4,8,12℃,and the connection of sprouting and flower regulation.The results indicated that during low temperature storage,the higher storage temperature it was,the earlier terminal bud elongation in bulb.That was to say,the speeds of terminal bud and new roots elongation at 12℃ were faster than that at 8℃ and 4℃.Bulbs were planted after low temperature treatment,it was clear that there were significantly negative correlations between sprouting time or growth period and treating time of lily bulb stored at the same temperature from 4~12℃.With the increase of treating temperature and the prolongation of treating time,the uniformity of sprouting,plant height,stem diameter and flower of lily were improved.If the low temperature treatment was insufficient,the regularity of lily bulbs sprout,plantlet emergence and growth was bad,and they even could not emergence plantlet in the planting years,thus the growth periods were prolonged.The results above indicated that five-week storage was a suitable for the dormancy release of ＇Raizan＇ bulb.
