E.P. Ivanova1, L.L. Kirillova2, L.D. Smolygina1, O.P. Serdyuk1

The results of comparative studying effects of 4-hydroxyphenethyl alcohol — exometabolite of purple bacterium Rhodospirillum rubrum and synthetic cytokinin 6-benzylaminopurine on seed germination, growth, productivity and development of amaranth vegetable form (Amaranthus caudatus L.) and also on the set of their physiological-biochemical parameters are presented. It was established, that seeds treatment with solutions of investigated substances (10-6 М) led to similar positive effects in all studied indices in the plants growing from these seeds. The authors suggest to use the 4-hydroxyphenethyl alcohol as the growth cytokinin-like natural stimulator for improvement of seed grain and plant productivity.

Keywords: 4-hydroxyphenethyl alcohol, cytokinins, amaranth, seeds germination, ontogenesis, productivity, protein content.
