The chemical compounds that showed in concentrations 10-8M-10-9M/1 of distilled water high growth stimulating activity on growth and development of flax, pea and maize, as well as auxin, cytokinin and gibberellin-like activity according to specific bioassays conducted on isolated cotyledons of muscat pumpkin of cultivar Gilea in vitro and on hypocotyl and root of lettuce seedlings of cultivar Berlin in vivo were selected. It was found that growth stimulating activity of heterocyclic compounds was similar or exceeded the activity of natural and synthetic phytohormones auxins IAA and NAA, and cytokinin Kinetin. The application of selected compounds in the agricultural practice of Ukraine as new effective and environmentally safe plant growth regulators is proposed. Product Description popup.authors В.М.
