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.
