 Abstract. Sucrose is one of the major sources of carbon and energy to the culture media used for in vitro cultures of plants. In this article, was studied the influence of different sucrose concentrations on in vitro multiplication of the species Ribes rubrum (15 g/l, 30 g/l, 45 g/l, 60 g/l) on MS culture medium containing half macroelements supplemented with growth regulators BA (0.2 mg/l), IBA (0.01 mg/l) at pH=5.7–5.8. The highest multiplication rate was observed using theculture medium with a sucrose concentration of 45 g/l.

Key words: Ribes rubrum, sucrose concentration, micropropagation
