摘要:
以灰毛蓝钟花种子为试材，采用正交实验设计，研究了光照、赤霉素浓度、不同浸种时间处理对灰毛蓝钟花种子萌发情况的影响，以期提高灰毛蓝钟花种子的萌发率，增加高山植物在低海拔地区存活的机率。结果表明：灰毛蓝钟花种子在赤霉素浓度600 mg?L-1、光照12 h、浸种12 h或18 h时发芽率、发芽势以及发芽指数最大，种子萌发持续时间最长，种子开始萌发时间和萌发高峰期最短。灰毛蓝钟花种子不喜长时间光照，光照时间越长不利于种子发芽，黑暗处理对种子萌发有促进作用。浸种时间越长对种子损害越大，不利于种子萌发。
Abstract:
The seeds of Cyananthus inconus were used as test material,the effects of illumination，gibberellic acid(GA) concentration and different soaking time on the seed germination of Cyananthus incanus were studied by means of orthogonal test to improve the seed germination rate and increase the survival rate of alpine plants in low altitude areas.The results showed that germination potential and germination index were the largest，duration of seed germination was the longest，seed germination time and peak of germination were the shortest when Cyananthus incanus seed was in GA concentration 600 mg?L-1，light time 12 hours and seed soaking 12 hours or 18 hours.Cyananthus incanus seed germination was not interested in illuminating for a long time，illumination time was not conducive to seed germination，but dark treatment on seed germination would promote.The longer the soaking time on seed，the greater the damage was，which could not conducive to seed germination.
