云木香种子生物学特性研究

通过发芽试验研究了预处理、温度、光照、pH和贮藏时间对云木香种子萌发的影响。结果表明:云木香种子用冷水浸泡预处理可缩短发芽时间和提高发芽整齐度,最适萌发温度在20～25℃之间;种子萌发对光的敏感性不强,光照条件和黑暗条件发芽率没有差异;种子对pH值的适应范围很宽,pH值在5～13范围内均可萌发;最适贮藏时间为12个月。

Study on Biological Characteristics of Seed of Aucklandia lappa

The effects of different treatments such as pretreatment,temperatures,light,pH-value and storing time on seed germination of Aucklandia lappa were studied.The results indicated that the pretreatment of soaking the seeds with cold water could shorten the germination duration and improve the uniformity of seedlings;the best germinating temperature ranged from 20 ℃ to 25 ℃;the sensitivity of the seeds to light was not strong,and light or dark condition had little influence on the seed germinating rate;the adaptive capacity of seed germination to pH-value was wide(pH 5～13);the most suitable storing time for the seeds was less than 12 months.
