T
he 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 auxin-
like 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 14
th
-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 16

day-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
