Анотация: fungal cultures was determined by the treatment of buckwheat seeds as biological test-object. For evaluation of growth-regulating activity of the extracts tested, the technique of germinating seeds in Petri dishes on filter paper and in rolls of filter paper was used. Plant growth-regulating activity of crude fungal extracts was strongly strain-dependent. Sixteen crude fungal extracts of Aspergillus recifei, Penicillium brevicompactum, P. chrysogenum, P. islandicum, P. restrictum, Beauveria bassiana, B. brongniartii isolates exhibited the most inhibition effect on buckwheat germs root growth (50-70 %). Sterigmatocystin isolated from A. versicolor inhibited buckwheat root growth by 32 %. Six crude extracts of fungal strains belonging to the species Cosmospora butyri, P. bilaii, A. fuci, A. recifei had the slight growth stimulation effect (20 %). The data about effect of austalids, diorcinols and sterigmatocystin on plant root growth have been obtained for the first time. It was shown that marine fungi could be used as potential sources of compounds with a plant growth-regulating activity.
