摘要： 利用含不同浓度2,4-D的修改的MS培养基对7个甘薯(Ipomoea batatas Lam.)品种进行茎尖脱毒培养,产生了形态和解剖特征明显不同的3种愈伤组织,胚性愈伤组织的诱导频率与品种和2,4-D浓度有关。将胚性愈伤组织转移到不含激素的修改的MS培养基上,有3个品种的胚性愈伤组织进一步发育成鱼雷胚和子叶胚。其中高淀粉品种苏薯2号的子叶

Abstract: The detached shoot tips of 7 sweet potato genotypes were cultured onmodified MS medium with various concentrations for the elimination of virus. 3morphologically and anatomically distinct types of calli were obtained. It was foundthat the inducement frequently of embryogenic calli was related to the
