摘　　要：以金线莲(Anoectochilus roxburghii)试管苗带节茎段和顶芽为外植体,用正交试验筛选芽快速增殖的培养基配方,并研究生根粉(ABT)对促根壮苗的作用。结果表明,丛生芽增殖最佳配方为MS+BA 3.5mg/L+KT 1.5mg/L+NAA 0.6mg/L,两个月增殖倍数达3.5;3mg/L 3号生根粉对金线莲生根壮苗效果最佳,使植株生根条数、最长根、植株增高和增叶数分别比对照增加12.8%、34.1%、13.2%和22.4%,从而提高移栽成活率,3种不同基质均达到94%以上。Taking stem segments and apical buds as explants, the optimal culture medium for rapid propagation of Anoectochilus roxburghii were carded out by orthogonal screening experiment. MS ＋ BA 3.5mg/L ＋ KT 1.5mg/L ＋ NAA 0.6mg/L gave the best result for multiplication of adventitious buds and proliferated buds for 3.5 times within 2 months. The growth media supplemented with ABT3 3mg/L increased the number of roots, the length of roots, the height of seedlings and the number of leaves by 12.8%, 34.1%, 13.2% and 22.4%, respectively.
