Abstract. The purpose. The study aims to investigate the influence of new arbuscular mycorrhiza (AM) fungi associations on the symbiosis development peculiarities in cucumber with different strains and plant growth and development. Methods. The experiment was conducted in pot culture with inorganic substrate with addition of calcium orthophosphate as the only source of phosphorus. Associations of AM fungi Funneliformis mosseae S1-4, F. mosseae 1-16 and F. mosseae 5-16, as well as Cucumis sativus L. variety Bjorn F1 were used. Results. It was observed that cucumber was selective to AM formation, as association 1-16 colonized roots more intensively with mycorrhizal colonization frequency of 68.9 % and arbuscule abundance of 44.2 % compared to associations F. mosseae S1-4 and F. mosseae 5-16. The study showed that colonization of C. sativus roots by new associations of AM fungi has a positive effect on plant productivity increasing root system mass by 83.3 % and shoot mass by 18.0–24.2 % compared to the control without treatment. Activation of plant growth processes is able to increase biological activity in their rhizosphere, creating favourable conditions for the development of microorganisms, as indicated by the increase in carbon dioxide emission by 23.7–43.5 % compared to the control. Scientific novelty. The peculiarities of AM formation in C. sativus depending on the applied association have been revealed. Agroand biochemical state of cucumber changing under the influence of AM and positively affecting plant productivity was analyzed. The association F. mosseae 1-16 is recommended for application in biotechnology of cucumber cultivation.
