Abstract

The auxin-like and cytokinin-like activity of chemical low molecular weight heterocyclic compounds, derivatives of pyrimidine, pyrazole, isoflavones, pyridine, oxazolopyrimidine and oxazole was studied. The specific bioassay on auxinlike activity conducted on the leaf petioles isolated from seedlings of haricot bean (Phaseolus vulgaris L.) cultivar Belozernaya showed high stimulating effect of the chemical heterocyclic compounds, derivatives of pyrimidine, pyrazole, isoflavones, and pyridine used at the concentration 10-8M on the formation of adventitious roots on the 14th-day-old leaf petioles isolated from seedlings of haricot bean (Phaseolus vulgaris L.) cultivar Belozernaya, which was similar or higher of the effect of plant hormones auxins IAA and NAA used at the same concentration 10-8M. The specific bioassay on cytokinin-like activity conducted on the cotyledons isolated from seeds of muscat pumpkin (Cucurbita moschata Duch. ex Poir.) cultivar Gilea showed the high stimulating effect of chemical heterocyclic compounds, derivatives of pyrimidine, pyrazole, isoflavones, pyridine, oxazolopyrimidine and oxazole used at the concentrations 10-8M and 10-9M on the growth of biomass of 16thday- old cotyledons isolated from seeds of muscat pumpkin (Cucurbita moschata Duch. et Poir.) cultivar Gilea, which was similar or higher of the effect of plant hormone cytokinin kinetin used at the same concentrations 10-8M and 10-9M. The obtained results confirmed the inducing auxin-like and cytokinin-like effect of synthetic heterocyclic compounds on plant cell elongation, division and differentiation that are the basic processes of plant growth.
