【摘要】 外植体来源不同的软紫草愈伤组织产生紫草色素的能力各异。６０Ｃｏ－ｒ射线辐照处理后的Ｈ２无性系愈伤组织生长量和色素产生均属上乘。改良ＭＳ基本培养基添加１毫克／升ＫＴ，０．５毫克／升ＩＡＡ，５％（Ｗ／Ｖ）蔗糖对愈伤组织培养较为适宜。马铃薯提取液对愈伤组织生长有明显的促进作用。更多还原

【Abstract】 Callus of various explants of Arnebia euchroma had different ability to produce shikonin. H2 clone which was treated by 60Co-r rays had higher production in both callus yield and shikonin than the others. A modified MS medium with 1 mg/l KT, 0.5 mg/l IAA, 5% sucrose stimulated production of callus and shikonin. Potato extract was benefit to callus production.更多还原
