对单叶省藤、短叶省藤组培快繁成苗芽的选择研究试验结果表明 :生长健壮、形态正常的不同高度未展叶单芽组 ,在成苗培养过程中 ,高生长、生根率、生根条数和生根长度存在差异。高度在2 .1～ 4 .0cm的未展叶单芽为伸长培养和生根诱导培养的最佳高度组 ,生根诱导培养 3个月后 ,芽苗生长可达到组培苗移植规格 (苗高、根长 >4 .0cm)。研究试验结果还显示 ,2种省藤组培成苗培养过程 ,伸长及生根诱导培养可浓缩为一步 ,直接从增殖培养材料中选择 2 .1～ 4 .0cm的单芽进入生根诱导培养 ,一步成苗
The study on the selection and propagation of the sprouting budlets from the leaves and leaves of the rattan and short leaves of rattan showed that the single shoots with different height and height at the same height had the highest growth rate and rooting rate, The rooting number and rooting length are different. The height of 2.1-1.4 cm single leaf buds for elongation and root induction culture the best height group, root induction culture 3 months after the bud growth can reach the tissue culture seedling transplant specifications (seedling height, root Long> 4 .0cm). The results of the research also showed that the cultivation process, elongation and rooting induction culture of the two kinds of rattan group can be concentrated in one step, and the single shoot of 2.1-4.0 cm was directly selected from the proliferation culture material to enter the root induction culture, Step into a seedling
