The results of research on stimulation of barberry cuttings (Berberis thunbergii DC) using vacuum infiltration technology for their forced saturation with water are presented. When soaking cuttings in a vacuum infiltrator in a rarefied medium (0.2 atmosphere), an increase in their weight by 7.1 % was recorded compared to the control (soaking in distilled water at atmospheric pressure) and twice as intense formation of axillary leaves. The nitrogen content of the treated and untreated cuttings was not significantly different. In the variant with vacuum infiltration, a statistically significant decrease in the content of phosphorus and potassium in the plant material and an increase in the content of disaccharides were noted, which indicates the intensification of biochemical processes.
