[目的]旨在探究200 mg·L−1浓度6-苄氨基嘌呤(6-BA)在不同浸泡时间处理下对多花黄精Polygonatum cyrtonema'丽精1号'、庆元种源多花黄精种子初生根茎出苗的影响.[方法]以多花黄精'丽精1号'、庆元种源多花黄精种子作为试验材料,用200 mg·L−16-BA分别进行1 h、2 h、4 h、6 h浸泡处理,以清水浸泡作为对照,重复3次,对各处理下多花黄精种子初生根茎的平均出苗率,出苗势,幼苗保存率进行统计分析.[结果](1)200 mg·L−1浓度下不同浸泡时间对两种多花黄精种子初生根茎出苗率存在显著影响:浸泡2 h多花黄精'丽精1号'和庆元种源多花黄精种子初生根茎出苗效果好,观测期间平均出苗率达到57.33%;(2)2 h浸泡处理对种子初生根茎出苗势有显著影响:'丽精1号'、庆元种源多花黄精种子初生根茎在2 h浸泡处理下种子平均出苗势最高,分别达到48.67%、50.67%;(3)不同时间浸泡处理对种子幼苗保存率影响:'丽精1号'、庆元种源多花黄精种子初生根茎在200 mg·L−16-BA浸泡2 h处理下平均幼苗保存率均超过90%,幼苗长势最好.[结论]200 mg·L−16-BA浸泡2 h对'丽精1号'、庆元种源多花黄精种子初生根茎出苗有显著作用,较传统出苗极大缩短了出苗时间,有效提高了出苗率及出苗保存率;该方法操作简单,经济成本低,可用于种苗培育过程中.
Preliminary Report on the Experiment of 6-BA Enhanced Germination of Multi-flowered Solomon's Seal Primary Rhizomes
[Objective]This study investigates the effects of treating seeds of Polygonatum cyrtonema cultivars 'Li Jing No.1' and Qingyuan source with 200 mg·L−16-Benzylaminopurine (6-BA) for varying soaking durations on the germination of their primary rhizomes.[Method]Seeds of Polygonatum cyrtonema 'Li Jing No.1' and Qingyuan source were used as experimental subjects. A 200 mg·L−16-BA solution was prepared for soak-ing treatments of 1,2,4,and 6 hours,with distilled water as the control. Each treatment was repeated three times to assess and compare the germina-tion rate,seedling vigor,and survival rate of the seedlings under different conditions.[Result]1. Soaking duration at 200 mg·L−1 significantly influ-enced the germination rate of primary rhizomes in both cultivars. A 2-hour soaking period yielded the best germination results,achieving an average germination rate of 57.33% for both 'Li Jing No.1' and Qingyuan source seeds. 2. Seedling vigor was significantly improved with a 2-hour treatment,with 'Li Jing No.1' and Qingyuan source seeds reaching vigor levels of 48.67% and 50.67%,respectively. 3. Soaking duration also affected the sur-vival rate of seedlings. Both 'Li Jing No.1' and Qingyuan source seedlings treated with 200 mg·L−16-BA for 2 hours had survival rates exceeding 90%,exhibiting optimal growth.[Conclusion]A 2-hour soak of Polygonatum cyrtonema seeds ('Li Jing No.1' and Qingyuan source) in 200 mg·L−16-BA significantly enhances germination rates,shortens germination time compared to conventional methods,and improves both seedling vigor and survival rates. This method is simple,cost-effective,and practical for seedling cultivation processes.
