The article presents the results of the research on the effect of processing cuttings grapes Moldova and Bianca by a growth regulator called Stimolant 66f (Stimolante 66f) on their regenerative properties, the yield and quality of seedlings. In Moldova grade, we tested three concentrations of the drug - 0.001; 0.01 and 0.1% and grade Bianca - five - - 0.001; 0.005; 0.01; 0.05 and 0.1%, compared to treatment with IAA (standard) or without treatment (control). It was found, that both types of processing cuttings with IAA led to the inhibition of blooming buds. Application of Stimolanta to both varieties accelerated blooming buds, and to the greatest extent on grade Bianca. On the variety Moldova, the processing cuttings with heteroauxin and Stimolant at 0.01 and 0.1% had an inhibitory effect on the growth of shoots, which survived to the end of the experiment. On the variety of Bianca, both the IAA and Stimolant at all concentrations of working solution contributed to a significant increase the length of the shoots. At grade Moldova, basal ends of cuttings treatment for 24 hours in solutions of Stimolanta at 0.01 and 0.1% concentration had the root-growing ability stimulated, enhanced the yield and quality of seedlings. In grade Bianca, better rooting of cuttings with 3 or more roots was observed in the variant of "Stimolant - 0.05%", and a greater number of roots were produced in the version of "Stimolant - 0.1%." In cuttings of varieties ofMoldova, Stimola
nt showed better results than the IAA in optimal concentrations, and grade Bianca had about the same results
