The paper presents data on the caffeine’s effect on microplants. As part of the rooting medium, caffeine can produce both positive and negative effects, depending on the concentration. The most effective range of caffeine concentrations in a nutrient medium, when plants of the Rubus genus are rooting, was determined – from 1 to 100 mg/l. The use of caffeine in optimal concentration enabled the acceleration of roots growth, increase in rooting frequency, and the number of roots per rooted microcuttings. A concentration of caffeine in excess of 0.1% has a negative effect on plant tissues, slowing down and stopping the formation of roots, shoot growth and causing tissue necrosis.
