Abstract

The main objective aim of study was to improve the technology of clonal micropropagation using growth regulators. There were included in experiment the following varieties: Augustine, Moldova, Vostorg, Muscat Italian, Early Magaracha, Gift of Magaracha, Viorica. Auxins and cytokinins in various concentrations and combinations were added into the culture medium as growth regulators. The conducted experiments showed the shoots regeneration of isolated apexes occurred at all concentrations of 6-BAP except additive formulation in an amount of 5.0 mg/l when the tops immediately began to blacken and died. Effective influence of 6-BAP concentrations was in the range of 0.5...1.0 mg/l. Nevertheless, the greatest increase of microshoots fixed in the embodiment with a concentration of 1.0 mg/l should be noted. To speed up the process of microshoots lengthening, the study of the gibberellic acid effect in different concentrations combined with 6-BAP was simultaneously conducted. The experience has shown that the combination of 0.5 mg/l 6-BAP+1.0 mg/l (GA) achieved the best result.
