非洲紫罗兰组织培养体系的建立

     

摘要

以紫色白边单瓣花的非洲紫罗兰叶片为试材进行了组织培养技术的研究。结果表明:以叶片为外植体进行组织培养时,愈伤组织诱导最适培养基为MS+0.2 mg/L NAA+0.5 mg/L6-BA,培养3周左右诱导率达100%;继代增殖时最适培养基为MS+0.02 mg/L NAA+0.1 mg/L 6-BA;无需生根培养,直接瓶外炼苗,栽植于以m (草炭土)∶m(珍珠岩)=1∶1的基质中生长最好,成活率可达95%以上。%We studied the tissue culture technology of Saintpaulia Ionantha with the purple petals of white edge and single flower . The tissue culture was conducted with the leaves as explants .The inducing medium for callus was MS+0.2 mg/L NAA+0.5 mg/L 6-BA.The induction rate after three weeks was100 %.The most suitable medium for subculture was MS+0.02 mg/L NAA+0.1 mg/L 6-BA.The outk-tube rooting rate were relatively better without taking root in the bottle .The best matrix for planting effect was peat soil and perlite with the mixed proportion of 1∶1 and the survival rate of >95%.
