摘  要:
[目的]探讨满天星组培苗生长适宜的GA3浓度和腺嘌呤浓度。[方法]采用云南省农业科学院花卉研究所组培中心继代培养2代的满天星品种‘小仙女’组培苗为材料,切取1 cm左右的带芽茎段为外植体,在MS+BA 0.3 mg/L+NAA 0.1 mg/L培养基中分别加入0.3、0.5、1.0、1.5、2.0 mg/L的腺嘌呤和赤霉素(GA3)进行研究。[结果]腺嘌呤、GA3具有促进满天星组培苗生长的作用,腺嘌呤适宜的使用浓度为1.5 mg/L;GA3适宜的使用浓度为1.0 mg/L。在同等条件下,腺嘌呤对满天星组培苗生长的促进作用比GA3效果好。[结论]为今后大力发展满天星组培苗奠定基础。

摘  要:
[Objective]The aim was to discuss the suitable GA3 and ademine concentration of Gysophila paniculata seeding growth.[Method]Using 2 generations Gysophila paniculata‘fairies' seeding subcultured by Tissue Culture Center of Yunnan Province Academy of Agricultural Sciences Institute as material,cutting out 1 cm long with bud stem segments as explants,MS + BA 0. 3 mg /L + 0. 1 mg /L NAA medium adding respectively 0. 3,0. 5,1. 0,1. 5,2. 0 mg /L of adenine and gibberellic acid( GA3) were studied. [Result]Adenine,GA3 had the role of promoting the growth of Gysophila paniculata. The appropriate concentration of adenine was 1. 5 mg /L,and the suitable concentration of GA3 was 1. 0 mg /L. Under the same condition,Adenine was better than the effect of GA3 on promoting growth effect of Gysophila paniculata.[Conclusion] The study laid a foundation for developing Gysophila paniculata seeding in the future.
