独蒜兰快繁技术的研究

研究结果表明,独蒜兰组织培养最好选用种子萌发的幼芽体进行.激素的种类和浓度影响愈伤组织的形成,在2,4-D 2 mg*L-1 6-BA 0.25 mg*L-1和2,4-D 2 mg*L-1 KT 0.25 mg*L-1的MS培养基中,外植体的死亡率较低;高浓度的2,4-D有利于快速形成大量的愈伤组织,但愈伤组织褐变死亡率较高;无论是种子萌发的芽还是从假鳞茎上剥下的芽,在6-BA 2 mg*L-1的MS上其长势都是最好;6-BA 2 mg*L-1最适合外植体为种子萌发的芽的增殖,当6-BA浓度为4 mg*L-1时,则抑制了外植体的芽的增殖与生长;NAA对外植体的芽的增殖和生长都有抑制作用;MS 6-BA 3.0 mg*L-1 NAA 0.5 mg*L-1培养基对不同外植体芽的增殖倍数有显著性差异;添加了IBA的培养基有利于根系的诱导.
