| 摘 要： | 发根农杆菌（Ａ．ｒｈｉｚｏｇｅｎｅｓ）Ｒ１５００感染龙胆茎段、叶片外植体，１５ｄ后可诱导出毛状根。茎段诱导率高于叶片，可达４２．３％。毛状根的诱导与温度和光照有关。转化根具有抗卡那霉素的特征，在不含激素的ＭＳ培养基上培养，筛选出了生长正常的毛状根系。

| Abstract: | Stem and leaf explants of Gentiana manshurica Kitag were infected with Agrobacteium rhizogenes strain R1500 and hairy roots were induced from the infected explants 15 days later.Frequency of stem-induction amounted to 42 . 3 % 'which was higher than that of leaf-induction. Hairy root induction was related to temperature and illumination.Hairy roots grew well in hormore-free MS agar medium and the transformed roots were resistant to kanamycin. |
