| Abstract: | It is necessary to establish an efficient regenerating system before genetic transformation of grapevine. In this study, an efficient regenerating system was established. Adventitious buds were obtained from the leaves of `Red Globe'( Vitis vinifera L.), and the factors that affect adventitious bud regeneration were studied. The regenerating rate of adventitious bud had relationship with the kinds and the concentration of plant growth regulator, leaf position, etc. The optimum medium for adventitious bud regeneration was found, which is NN 69 +BA 2.0 -2.5mg/L+IBA 0.2mg/L. The regenerating rate of the adventitious bud from the first top leaf was the highest. |
