- 摘要:
- 以云锦杜鹃(Rhododendron fortunei Lindl.)种子为试材,通过设置不同的消毒试剂及不同激素的组合,筛选出云锦杜鹃种子的最佳消毒方法和云锦杜鹃种子在萌芽、增殖、壮苗、生根过程中的最适激素配方,建立云锦杜鹃种子组培快繁体系,以期为实现种质资源保存、引种驯化、快速繁殖,并为产业化应用提供参考依据。结果表明:最佳消毒方法为75%乙醇30 s+3%次氯酸钠溶液12 min,该消毒法可实现种子零污染并保证种子发芽;最适萌芽培养配方为WPM培养基+5.0 mg·L-1GA3,其发芽率高达81.00%±6.52%;最适增殖培养配方为WPM培养基+0.4 mg·L-1TDZ+1.0 mg·L-1IBA,其增殖系数达到5.50;最适壮苗培养方法为WPM培养基+0.2 mg·L-1TDZ+0.4 mg·L-1IBA,30 d内无菌苗的苗高增量达到7.59 mm;最适生根培养配方为不加任何激素的WPM培养基,其生根率达到50.00%±17.57%。
- Abstract:
- Taking Rhododendron fortunei Lindl.seeds as the experimental material,the best disinfection method of Rhododendron fortunei Lindl.seeds and the optimum hormone formula of Rhododendron fortunei Lindl.seeds in the process of germination,proliferation,strong seedling and rooting were screened out by setting different disinfection reagents and different hormone combinations.Establish a tissue culture and rapid propagation system of Rhododendron fortunei Lindl.seeds,the preservation of germplasm resources,introduction and domestication,rapid propagation were realized,in order to provide reference for industrial application.The results showed that the best disinfection method was 75% ethanol 30 seconds+3% sodium hypochlorite solution 12 minutes.This disinfection method could achieve zero seed pollution and ensure seed germination.The optimum germination culture formula was WPM medium+5.0 mg·L-1GA3,and the germination rate was as high as 81.00%±6.52%.The optimal proliferation culture formula was WPM medium+0.4 mg·L-1TDZ+1.0 mg·L-1IBA,and the proliferation coefficient reached 5.50.The optimum seedling culture method was WPM medium+0.2 mg·L-1TDZ+0.4 mg·L-1IBA,and the seedling height increment of sterile seedlings reached 7.59 mm within 30 days;the optimum rooting culture medium was WPM medium without any hormones,and the rooting rate reached 50.00%±17.57%.
