ABSTRACT
The impact of the merosesquiterpenoids avarol (1), avarone (2), 18-methylaminoavarone (3), melemeleone A (4), isospongiaquinone (5), ilimaquinone (6), and smenoquinone (7), isolated from marine sponges of the Dictyoceratida order, was studied on the root growth of seedlings of buckwheat (Fagopyrumesculentum Moench), wheat (Triticumaestivum L.), soy (Glycine max (L.) Merr.), and barley (Hordeumvulgare L.). Compounds 2and 6 were effective for the root growth of wheat seedlings, compound 3 stimulated the root growth of seedlings of buckwheat and soy, compound 4 affected the roots of barley seedlings, and compound 5 stimulated the root growth of seedlings of buckwheat and barley. Compounds 1 and 7 showed no activity on the root growth of the seedlings of any of the studied plants. The stimulatory effect depends on the chemical structure of the compounds and the type of crop plant.

N-Methylpretrichodermamide B (I), pretrichodermamide C (H), quinolactacide (III) and 8-methoxy-3,5-dimethyl-3,4-dihydro-IH-isochromen-6-ol (IV), isolated from the marine fungus Penicillium sp., were examined for their ability to stimulate growth of seedling roots of buckwheat (Fagopyrum esculentum Moench), wheat (Triticum aestivum L.), soy {Glycine max (L.) Merr.}, and barley (Hordeum vulgare), It was shown that the stimulatory effects depend on the chemical structure of the compounds and on the plant species. Compounds I and III improved the rate of growth of seedling roots of buckwheat (1) and wheat (2), compound II stimulated growth of buckwheat roots (1), and compound IV improved growth of seedling roots of wheat (2) and soy (3). These compounds can be recommended for field study as plant growth stimulators.

Oxirapentyn A (1), oxirapentyn B (2), and oxirapentyn E (3) were examined for their ability to stimulate growth of seedling roots of barley (Hordeum vulgare L.), buckwheat (Fagopyrum esculentum Moench), corn (Zea mays L.), soy {Glycine max (L.) Merr.}, and wheat (Triticum aestivum L.). It was shown that the stimulatory effects depend on the chemical structure of the oxirapentyns and on the plant species. Compounds 1, and 2 are efficient for growth of seedling roots of barley, and wheat, whereas compound 3, at different concentrations, stimulates growth of seedling roots of maize, soy, and wheat. These compounds can be recommended for field study as plant growth stimulators.

Damirone A (1), damirone B (2), makaluvamine G (3), debromohymenialdisine (4), and dibromoagelaspongin (5) were examined for their ability to stimulate growth of seedling roots of barley (Hordeum vulgare L.), buckwheat (Fagopyrum esculentum Moench), corn (Zea mays L.), soy (Glycine max (L.) Merr.}, and wheat (Triticum aestivum L.). It was shown that the stimulatory effects depend on the chemical structure of the alkaloids and on the plant species. Compounds 1, 3, and 4 are efficient for growth of seedling roots of barley, compounds 2-5, at different concentrations, stimulate growth of buckwheat roots, and compound 5 stimulates growth of wheat roots. These compounds can be recommended for field study as plant growth stimulators.
