- 摘要:
- 为促进小檗属的引种栽培,以喀什小檗、红果小檗和小檗3种小檗属植物种子为材料,研究不同前处理对3种小檗种子萌发的影响。结果表明:与对照相比,研磨和浓硫酸处理均使3种小檗种子的萌发启动时间提前,并显著缩短了萌发持续时间,日均增长生物量也有所提高,种子体现出了集中萌发的特点,萌发和生长速度较快,是3种小檗种子萌发的最佳处理方式;200 mg?L1赤霉素浸种处理使红果小檗种子的萌发率显著下降,但对萌发启动时间和萌发持续时间影响不大;清水浸泡24 h处理显著降低了喀什小檗种子的萌发率,并延迟了萌发启动时间,延长了萌发持续时间,大大降低了日均增长生物量。
- Abstract:
- In order to promote the introduction cultivation of the Berberis,the effects of different pretreatment on the seed germination of three species of Berberis?were studied.The results showed that compared with the control,the germination initiation time of three kinds of Berberis?seeds under grinding and concentrated sulfuric acid treatment was advanced,and the germination duration was shortened significantly,the daily growth biomass was also improved,and the seeds showed the characteristics of concentrated germination.The germination and growth rate were faster.Grinding and concentrated sulfuric acid treatment were the best pretreatment for three species of Berberis germination.The seed germination rate of B.nummularia Bge.under 200 mg?L1 gibberellin pretreatment was significantly decreased,but the germination inltiation time and the duration of germination was not significant.The germination rate of the seeds of Berberis kaschgarica?Rupr.was decreased for 24 h water treatment and it delayed the initiation time of germination,prolonged the germination duration,and greatly reduced the daily growth of biomass.
