Е. Г. Самощенков The relevance of this work stems from the need to obtain a large amount of planting material for establishing and renewing commercial orchards. Accelerated propagation of rootstocks for stone fruit crops will contribute to the development of the fruit growing industry. This article presents two-year data on the aerosol application of 4-(indol-3-yl)butyric acid (IBA) for rooting herbaceous cuttings of clonal stone fruit rootstocks: OP 23–23, VSL-2, and plum cultivar Eurasia 21. Prepared herbaceous cuttings were tied into bundles, their basal ends immersed 1–1.5 cm deep in a container with distilled water, and then placed in a film chamber for aerosol treatment lasting 4 to 20 hours. The aerosol was generated using an ultrasonic humidifier connected to a timer. The operating mode was cyclic, with mist generation for one minute followed by a 9-minute interval. The working solution of the rooting stimulant (25 mg/l) was prepared from “Koren Super”, WDG (5 g/kg indolyl-3-butyric acid) produced by Avgust, AO. An increase in rooting success was observed across all treatments. The best rooting rate was achieved with 16–20 hours of exposure, reaching 97.7 %, which is 10–11 % higher compared to the control. The number of first-order roots significantly increased, but their average length increased only slightly. The average length of new growth noticeably increased. A significant difference in the average number of new shoots was observed only for rootstock OP 23–23 with 20 hours of exposure in 2024.
