摘要
以香果树(Emmenopterys henryi Oliv.)实生苗带芽茎段和叶片为外植体进行组织培养。结果表明,香果树带芽茎段愈伤组织的最适诱导培养基为含有1.0mg·L^-1~6-BA和0.01mg·L^-1 NAA的MS培养基,愈伤组织诱导率达100%;愈伤组织分化的最适培养基为添加2.0mg·L^-1KT和0.01mg·L^-1 NAA的MS培养基;在含有1.0mg.L^-1~6-BA和0.1mg·L^-1 NAA的MS培养基上,叶片诱导不定芽的效果较好,诱导率可达80%;在含有2.0mg.L^-1 KT和0.1mg·L^-1 NAA的MS培养基上,不定芽的增殖系数可达3—4;以含有1.5mg·L^-1 IBA的1/2MS培养基为生根培养基,香果树试管苗生根率达72.73%。移栽至大田后,香果树试管苗的成活率达到30%。
Tissue culture of Emmenopterys henryi Oliv. has been investigated using leaf and stem as explants. The results show that MS medium containing 1.0 mg· L^-1 6-BA and 0.01 mg · L^-1 NAA is suitable for inducing callus from stems, the induced rate reaches to 100%. MS medium containing 2.0 mg · L^-1 KT and 0.01 mg · L^-1 NAA is the best suitable medium for callus differentiation. On MS medium containing 1.0 mg · L^-1 6-BA and 0.1 mg · L^-1 NAA, inducement effect of adventitious shoot from leaf is better and the induced rate reaches to 80%. The perfect medium for adventitious shoot proliferation is the MS medium containing 2.0 mg · L^-1 KT and 0.1 mg · L^-1 NAA and the proliferation coefficient reaches to 3 - 4. Rooting rate of E. henry/ plantlets can reach to 72.73% by using 1/2MS medium containing 1.5 mg · L^-1 IBA as rooting medium. Survival rate of E. henry/ plantlets is about 30% after transplanting to field.
