Abstract
A series of (E) - 4 - arylacryloyl - 3,5 - dimethyl - 1H - pyrrole - 2 - carboxylic acids have been synthesized by condensation of 4-acetyl-3,5-dimethyl-1H-pyrrole-2-carboxylic acid with aromatic aldehydes. The issue of solubility of the synthesized substances for their use as preparations of agrochemical appointment is resolved. Physiological researches in the laboratory were carried out on the effect of aqueous solutions of the sodium salts of these compounds on germination energy, germination and biometric parameters on seeds of the sources Dzherelo, Phoenix, IR-7019, and rye of the winter variety Dihar of different viability. Statistical analysis of the results of the research by the method of analysis of variance was performed. It is authentically defined the activity of stimulators of growth of the offered compounds. The activity of growth-promoting factors depends by nature compound and on specifics of a grade of seeds. The most effective in germination energy, seed germination, seed weight, root length and root mass are arylpropenoylpyrrolecarboxylic acids containing a halogen atom and a methoxy group in the phenyl nucleus. Technological approaches have been proposed for the production of effective stimulators of seed germination.
