The effect of decumbenones A (1), B (2) and C (3) from the marine-derived strain of the fungus Aspergillus sulphureus on the growth of seedling roots of buckwheat, wheat, barley and corn at the concentration range 10^﹣5 - 10^﹣18 M was studied. It was shown that decumbenone B had a stimulatory effect on the growth of seedling roots of buckwheat, decumbenone A—on the growth of seedling roots of spring soft wheat, decumbenone C—on the growth of seedling roots of spring barley, decumbenone A, B and C —on the growth of seedling roots of corn. The stimulatory effect for some substances was shown at ultra-low concentrations 10^﹣12 - 10^﹣18 M. It is possible to recommend decumbenones A, B and C for studying in field conditions as growth factors of buckwheat, wheat, barley and corn.
