紫外辐射能显著地降低人参培养细胞单细胞克隆的植板率。当紫外辐射悬浮细胞３０ｓ后，细胞克隆的植林率是对照组的２１．４３％。细胞克隆平板培养６０ｄ，挑取克隆连续转移培养３次，共获得克隆系１２２株。对所有克隆系进行变异分析并经１０代连续继代培养，从中筛选到一株稳定的高产寡糖素克隆系ＰＧＵＡ－０８，而且它的过氧化物酶同工酶谱特征也保持稳定。克隆系ＰＧＵＡ－０８的生长速率为０．５３７ｇＤＷＬ－１ｄ－１，是亲本的１．４６倍，寡糖素含量为１７．１６％ＤＷ，是亲本的１．８１倍，寡糖素产率为２．７６４ｇ／Ｌ，是亲本的２．６２倍。
UV radiation can significantly reduce the ginseng cultured cells unicellular clonal plating rate. When the cells were suspended by ultraviolet radiation for 30s, the rate of cell colonization was 21.43% of the control group. The cell clone plate culture 60d, picked the clone continuous transfer culture three times, a total of 122 clone lines were obtained. All of the clones were subjected to mutation analysis and subcultured successively for 10 generations, and a stable high-yielding oligosaccharides clone PGUA-08 was screened out, and its peroxidase isozyme profile was also stable. The growth rate of clone PGUA-08 was 0.537gDWL-1d-1, which was 1.46 times of that of the parent, the content of oligosaccharides was 17.16% DW, which was 1.81 times of the parent, the yield of oligosaccharides was 2.764g / L, 2.62 times that of the parent.
