摘　　要：以香叶天竺葵的幼叶为外植体,进行组培快繁技术研究。结果表明:在MS+6-BA 1.0 mg·L^(-1)+NAA 0.1 mg·L^(-1)的培养基上进行香叶天竺葵不定芽诱导,不定芽分化率84.4%;在MS+6-BA 1.0 mg·L^(-1)+NAA 0.5 mg·L^(-1)的培养基上进行继代培养,其增殖倍数达11.7倍;采用1/2 MS+IBA 0.5 mg·L^(-1)的培养基进行生根培养,香叶天竺葵幼苗生根率100.0%,且植株健壮,经炼苗后移栽成活率95.0%以上。The young leaves of Pelargonium graveolens were chosen as explants to study rapid sterile propagation techniques.The results indicated that the medium MS+6-BA 1.0mg·L^(-1)+NAA 0.1mg·L^(-1)was the most appropriate for induction of adventitious buds,with the differentiation rate reaching 84.4%.The highest multiplication rate of subculture was 11.7 as the medium MS+6-BA 1.0 mg·L^(-1)+NAA 0.5 mg·L^(-1)was used.When 1/2 MS+IBA 0.5mg·L^(-1)was used for rooting culture,the rooting rate reached 100.0%,and the plants were strong.The survival rate of transplanting was over 95.0%after the seedling training.
