The results of studies on the regeneration ability of green and semi-woody cuttings of plants of the genus Cotoneaster Medic. for obtaining high-quality planting material are presented. The effect of plant growth stimulants (Heteroauxin, Epin +, Kornevin, Charkor) on rooting and biometric indicators of cuttings in protected soil conditions in different substrates peat + sand 2:1 (pH 4.8), sand (pH 5.7), peat substrate Mixkar MKS-10-6 (pH 5.2-6) was analyzed. The object of the study was represented by five species of Cotoneaster - Cotoneaster ascendens Flink & B. Hylmö, Cotoneaster hjelmqvistii Flinck & B. Hylmӧ, Cotoneaster horizontalis Decne., Cotoneaster nan-shan M.Vilm. ex Mottet, Cotoneaster dammeri C.K.Schneid, which are characterized by high decorativeness and are in demand, which requires maximum efficiency of vegetative propagation and cultivation in the conditions of the Right-Bank Forest-Steppe of Ukraine. Therefore, finding new technologies and improving existing ones for vegetative propagation of species of genus Cotoneaster is an extremely urgent task that requires a scientific solution.
