- 摘要:
- 以沙姜芽为外植体,研究不同因子对沙姜消毒、增殖、生根的影响,以期建立沙姜组培快繁体系,并为其脱毒技术研究提供参考。结果表明:沙姜芽使用75%酒精60 s+0.1%升汞(HgCl2)8 min灭菌效果最好,污染率为13.33%,成活率达86.67%;不同激素组合对沙姜不定芽的继代增殖效果各异,以2.00 mg?L-16-BA+0.25 mg?L-1NAA的激素配比的增殖效果最好,增殖系数为6.30,沙姜组培苗最佳的生根培养基为1/2MS+NAA 0.50 mg?L-1,平均生根数为15.32条。
- Abstract:
- The bud of Kaempferia galangal were was used as the materials,to study the effect of different factors on the disinfection,multiplication,root induction,so as to establish in vitro culture system and provide reference for detoxification.The results showed that the best disinfection method of the bulb explants of Kaempferia galangal was 75% ethanol for 60 seconds,followed by 0.1% HgCl2 8 minutes,the contamination rate was 13.33%,and the survival rate was 86.67%.The effects of hormones on proliferation of adventitious bud were diffferent,the appropriate medium for proliferation was MS+6-BA 2.00 mg?L-1+NAA 0.25 mg?L-1 with the multiplication coefficient of 6.30.The best medium for root induction was 1/2MS+NAA 0.50 mg?L-1 and the number of roots per plantlets was 15.32.
