- 摘要:
- 以洋甘菊(Matricaria chamomilla L.)的嫩茎和幼叶为外植体,采用单因子试验方法,研究不同消毒措施、不同激素浓度配比对洋甘菊愈伤组织诱导的影响,以期为建立洋甘菊再生体系以及通过基因工程手段改良洋甘菊提供参考依据。结果表明:洋甘菊幼嫩的茎段为组织培养的最佳外植体材料,愈伤组织的诱导率高达90%;以幼嫩茎段为外植体,最佳灭菌措施为新鲜的嫩茎用无菌水冲洗30 min,75%的酒精浸泡10 s,3 5%的次氯酸钠浸泡10 min,诱导率高达86 7%,污染率低至13 3%;其愈伤组织诱导的最佳培养基为MS+6-BA 1 5 mg?L-1+NAA 1 2 mg?L-1。
- Abstract:
- Young stems and young leaves of Matricaria chamomilia were used as explants,by adopting the method of single factor experiment,the influence of different disinfection measures and different hormone concentrations on callus induction of M.chamomilla was studied,in order to establish M.chamomilla regeneration system and genetic engineering methods.The results showed that young stems were the best explants for tissue culture with a high level of callus forming rate of 90%.The best condition of sterilization with young stems was as follow:fresh young stems wash under sterile water for 30 minutes,followed with 75% alcohol for 10 seconds and then 3 5% sodium hypochlorite for 10 minutes,the induction rate was as high as 86 7%,pollution rate was as low as 13 3%;the best medium for callus induction was MS + 6-BA 1 5 mg?L-1 + NAA 1 2 mg?L-1.
