为促进牛耳秋海棠的快繁及工厂化生产,以牛耳秋海棠的叶片为外植体,对其离体再生培养技术进行了研究。结果表明:牛耳秋海棠最佳消毒方法为75%酒精消毒8 s ,0.1%的HgCl2消毒6~7 min(滴加一滴吐温);牛耳秋海棠愈伤组织诱导和分化的最佳培养基为MS+6‐BA0.5~1.0 mg·L‐1+ NAA0.1 mg·L‐1,诱导率达85.42%~87.08%;牛耳秋海棠不定芽增殖的最适宜培养基是MS+6‐BA1.0 mg·L‐1+ NAA0.1 mg·L‐1,增殖倍数高达42.43。
為促進牛耳鞦海棠的快繁及工廠化生產,以牛耳鞦海棠的葉片為外植體,對其離體再生培養技術進行瞭研究。結果錶明:牛耳鞦海棠最佳消毒方法為75%酒精消毒8 s ,0.1%的HgCl2消毒6~7 min(滴加一滴吐溫);牛耳鞦海棠愈傷組織誘導和分化的最佳培養基為MS+6‐BA0.5~1.0 mg·L‐1+ NAA0.1 mg·L‐1,誘導率達85.42%~87.08%;牛耳鞦海棠不定芽增殖的最適宜培養基是MS+6‐BA1.0 mg·L‐1+ NAA0.1 mg·L‐1,增殖倍數高達42.43。

In order to improve the rapid propagation and factory production of Begonia sanguinea Raddi ,taking leaves of Begoniasanguinea Raddi as explants ,the tissue culture of Begoniasanguinea Raddi was studied .The results showed that the optimum sterilization time of explants were 8 s by 75% alcohol and 6~7 min by 0 .1%mercuric chloride with a drop of Tween;The optimized medium for callus induction and differentiation was MS+6‐BA 0 .5~1 .0 mg·L‐1 +NAA 0 .1 mg·L‐1 ,the induction rate was 85 .42% ~87 .08% ;The optimal mul‐tiplication medium was MS+6‐BA 1 .0 mg·L‐1 +NAA 0 .1 mg·L‐1 ,the multiplication coefficient was as high as 42 .43 .
