摘要
目的:探讨不同浓度IBA(吲哚丁酸)及浸泡时间对药用植物金钱草水插生根的影响,为其繁殖栽培提供理论和实践依据。方法:以金钱草的老熟茎段作插穗,在0(清水对照)、20、40、60 mg·L^(-1)IBA溶液中将插穗浸泡3、6、9、12 h后进行水插,观测其生根的各项指标。结果:IBA对金钱草插穗生根有明显促进作用,且以40 mg·L^(-1)IBA浸泡9 h的插穗生根指标最高,生根率达到100%,不定根数7.9条,不定根长49.7 mm,侧根数3.3条,根系发育指数达到43.2。结论:促进金钱草水插生根的最佳IBA浓度为40 mg·L^(-1),最佳插穗浸泡时间为9 h。
Objective： Lysimachia christinae was taken as the experimental material in order to provide theoretical and practical basis for its reproduction and culture in this study. Methods： The cuttings of L. christinae were treated in the wa- ter cutting propagation with IBA at the concentration of 0, 20, 40 and 60 mg L- l and soaking time of 3, 6, 9 and 12 h for examining rooting indexes. Results： IBA（ Indole Butyric Acid）could extremely promote cutting rooting of L. christinae. The roo- ting effect of the treatment of 40 mg L-1 and soaking 9 h was the best one in whole treatments and its rooting percentage, ad- ventitious root number, adventitious root length, lateral root number and developing indexes were 100%, 7.9, 49.7, 3.3 and 43.2, respectively. Conclusion ： The best treatment for the cutting rooting of L. christinae was 60 mg L-1 IBA solution with 9 h soaking time.
