摘要
薰衣草种子休眠期长且自然萌发困难,为提高薰衣草种子的发芽率,以薰衣草常见品种“孟士德”和“希德”为研究对象,通过设置不同温度处理、不同赤霉素浓度及不同浸泡时间的处理来研究温度和赤霉素处理对薰衣草种子萌发的影响。结果表明,薰衣草发芽最适温度因品种而异,“孟士德”在18℃时种子发芽率为81.67%,“希德”在21℃时发芽率达到最高,为70.67%。赤霉素浓度和不同浸种时间对薰衣草种子萌发存在显著影响,100μg/mL GA3浸泡处理6~8 h最有利于薰衣草种子发芽。
Lavandula angustifolia Mill.seeds have a long dormancy period and are difficult to naturally germinate.In order to improve the germination rate of Lavandula angustifolia Mill.seeds,common Lavandula angustifolia Mill.varieties'Monster'and'Sid'were used as research objects.The effects of temperature and gibberellin treatment on Lavandula angustifolia Mill.seed germination were studied by setting different temperature treatments,different concentrations of gibberellin,and different soaking times.The results showed that the optimal temperature for lavender germination varied depending on the variety.The seed germination rate of'Monster'was 81.67%at 18℃,and the highest germination rate of'Sid'was 70.67%at 21℃.The concentration of gibberellin and different soaking times had a significant impact on the germination of lavender seeds.Soaking with GA 3 at a concentration of 100μg/mL for 6-8 hours was most beneficial for Lavandula angustifolia Mill.seed germination.
