摘要: 应用组织培养及快速繁殖技术对斑叶兰(Goodyera schlechtendaliana Rchh. f.)芽的诱导和丛生芽的增殖复壮进行研究。研究发现,随着6-BA浓度的提高,斑叶兰芽增殖率上升,以6-BA 4.0 mg/L处理的增殖率最高;添加6-BA 4.0 mg/L+NAA 0.2 mg/L可将斑叶兰增殖控制在丛生芽阶段;添加100.0 g/L椰汁和0.5 g/L活性炭有利于提高斑叶兰增殖率与丛生芽的生长势,降低褐化;添加IBA 0.5 mg/L+NAA 0.5 mg/L+活性炭 0.5 g/L的1/2 MS基本培养基有助于斑叶兰生根且根系生长健壮。

Abstract: Rapid multiplication and tissure culture were used to study the induction of buds and the proliferation and rejuvenation of cluster buds of Goodyera schlechtendaliana Rchh. f.. The results showed that with the increase of 6-BA concentration, the shoot proliferation rate increased, and a maximum of proliferation was obtained at 4.0 mg/L 6-BA, and multiplication of shoots could be achieved and controlled by combination of 6-BA 4.0 mg/L and NAA 0.2 mg/L. The rate of muhiplieation and growth could be improved in media supplemented 100.0 g/L coconut juice(CJ) and 0.5 g/L activated charcoal(AC). Rooting of shoots were developed in 1/2 MS media with 0.5 mg/L IBA, 0.5 mg/L NAA and 0.5 g/LAC.

Key words: Goodyera schlechtendaliana Rchh. f., tissue culture, multiplication, rooting
