【摘要】 以MS培养基为基本培养基,附加NAA 0.05 mg/L和不同浓度的6-BA、KT、ZT,并以食用白砂糖代替分析纯蔗糖,以自来水代替蒸馏水对鸡蛋参进行增殖培养,比较生长状况。结果表明,6-BA、KT、ZT均能促进鸡蛋参单芽茎段的增殖,其中以ZT的效果最好;最适增殖培养基为MS+蔗糖30 mg/L+琼脂5.5 g/L+ZT 1.0 mg/L+NAA 0.05 mg/L;可以以食用白砂糖代替分析纯蔗糖,以自来水代替蒸馏水对鸡蛋参进行增殖培养。更多还原

【Abstract】 To select the optimum multiplication medium of Codonopsis convolvulacea Kurz,NAA、6-BA、KT and ZT were supplemented in MS basal medium,and sucrose of analytical pure was replaced by eatable sugar,distilled water was replaced by water.The study showed that 6-BA、KT and Zt could promote multiplication of stem segment with single bud.And ZT was the best of all.The optimum multiplication medium was MS,30 g/L sucrose,5.5 g/L agar,ZT 1.0 mg/L,NAA 0.05 mg/L.In addition,sucrose of analytical pure could be replaced by eatable sugar in the medium.更多还原
