摘要
通过蓝花大叶醉鱼草组培快繁的试验 ,研究了对外植体的不同取材部位及不同激素种类、浓度对芽诱导及培殖的影响。结果表明 :采用母株基部的茎段作外植体诱导率高 ,增殖系数大 ,在做不同激素的比较中 ,生长素起着决定因素。同时 ,筛选出最佳分化培养基MS +6 -BA1 0mg/l+IBA 0 0 5mg/l或MS +6 -BA 1 0mg/l+NAA 0 5mg/l,并对蓝花大叶醉鱼草组培中的一些问题进行了讨论。
This paper discusses the effects of different test types and concentrations of hormones on axillary bud and rapid propagation of Buddleja davidii.Experiment shows that the lateral axillary buds in vito culture of the stem near the roots has high ratio of axillary buds.It also sugests hormone play a vital role in rapid propagation of the plant.The experiment extablishes the best proliferations of axlliary buds is resulted in the medium MS+6-BA1 0mg/ L+IBA0 05mg/ L or MS+NAA0 05mg/ L+6-BA1 0mg/ L, and best rooting obtained in the medium 1/ 2MS+IBA0 5mg/ L or 1/ 2MS+NAA0 5mg/ L
