Studying on In Vitro Culture of Fujian Wild Grapes

In vitro culture technique of Fujian wild grapes was studied by using the stem-segment with node as explants.The results showed that their axillary buds could be induced in MS medium supplemented with 2.0mg.L-1 BA and 0.2mg.L-1 NAA,in which the induction rate was 72.2%.Considering multiplication coefficient and plantlet quality comprehensively,the medium MS or 1/2MS added with 2.0mg.L-1 BA and 0.2mg.L-1 NAA was the best for the proliferation of fascicular gemma with the propagation coefficient over than 3.0.For in vitro germplasm conservation of Fujian wild grape plantlets,the suitable medium was MS with 0.1mg.L-1 NAA and the plastochrone of subculture were about 5to 6mouths.Consequently,the growth ability of plantlets could be maintained vigorously.
