| 摘 要： | 采用改良DNS等方法筛选出的生长快、糖苷含量高的甜叶菊品系1096为材料,研究了不同外植体、不同激素种类和配比对愈伤组织诱导、不定芽分化和生根的影响。结果表明:以茎尖为外植体愈伤组织和不定芽诱导率均最高;其次是带腋芽茎段;再次为叶片。无腋芽茎段和无菌根均能诱导出愈伤组织,但不能诱导成芽。茎尖不定芽诱导的最佳培养基为MS+6-BA 1.0mg/L;叶片不定芽诱导的最佳培养基为MS+6-BA 1.0mg/L+IAA 1.0mg/L;带腋芽茎段不定芽诱导的最佳培养基为MS+6-BA 1.5mg/L。不定芽继代增殖培养采用MS+6-BA 0.5mg/L+NAA0.05mg/L;在1/4MS+IBA 0.1mg/L+NAA 0.1mg/L+1g/L活性炭的培养基上诱导生根,生根率可达100%,生根苗移栽后成活率达95%。

| Abstract: | The effects of different combinations of growth substances and explants on callus induction,bud differentiation and root formation were investigated in rapid growth and high steviol-glucosides content Stevia rebaudiana Bertoni Strain 1096,which was screened by improved DNS method.The results showed that stem apex seemed to be the best explant for callus induction and bud differentiation,followed by stem segment with axillary bud and the third was leaf.Both the stem segment without axillary bud and root of p... |
