摘　　要：在红叶石楠组织培养基中设置不同的萘乙酸(NAA)和6-苄基腺膘呤(6-BA)的浓度组合,研究其对不定芽和不定根的诱导效果。结果表明,在红叶石楠组织培养的芽诱导、芽增殖、根诱导阶段,分别采用NAA0.2mg/L+6-BA1.0mg/L、NAA0.4mg/L+6-BA1.5mg/L、NAA0.4mg/L浓度,可获得最佳的不定芽、根诱导效果。Different concentration combinations of NAA and 6-BA were setup in tissue culture media to study inducing effects of sprouts and roots of photiniafraseri. The result indicated that at the phases of sprout inducing, sprout reproduction and root inducing, the best inducing effects were obtained by using concentration combinations of NAA and 6-BA of NAA 0.2 mg/L＋ 6-BA 1.0 mg/L, NAA 0.4 mg/L＋ 6-BA 1.5 mg/L, NAA 0.4 mg/L, respectively.
