Abstract: The influence of arbuscular mycorrhizal fungi in the EC fertilizer Dynocarb MYC on the growth of 16 newly introduced cherry cultivars for the Kyustendil region - Primulat, Early Lorry, Sweet Lorry, Lorry Bloom, Big Lorry, Giant Red, Firm Red, Giorgia, Folfer, Early Star, Simcoe, Canada Giant, Skeena, Katalin, Sweetheart, Ferrovia, Bigarreau Burlat and Van was monitored. It was established that applying Dynocarb MYC positively affected the growth properties of the trees in all investigated cultivars. Regarding trunk diameter (cm²), differences compared to controls were positively demonstrated in Skeena, Firm Red, Early Star, Giant Red and Lorry Bloom. For the other cultivars, the differences were insignificant, but the tendency was positive. The trees of the treated variants were proven to be higher in the cultivars Early Lorry, Firm Red, Early Star, Sweetheart, Ferrovia, Skeena, Katalin, Lorry Bloom, Bigarreau Burlat, and Van. In the treated cultivars, a greater average length of annual shoots was found in the cultivars Early Lorry, Firm Red, Early Star, Sweetheart, Ferrovia, Skeena, Katalin, Lorry Bloom, Bigarreau Burlat and Van.
