IMPACT OF PLANT EXTRACTS ON THE GERMINATION OF SEEDS OF PINE, FIR, AND RADISH IN LABORATORY EXPERIMENTDMITRY I. PIGALIN, YURIY P. DEMAKOV, DMITRY A. KOREPANOV, YEVGENIY A. GONCHAROV AND MARIA N. CHEFRANOVAAbstract Higher plants synthesize organic substances with the help of mineral compounds. Accumulation of plants dry substance is carried out by fixation of carbon dioxide via leaves, which is called photo synthesis. Water, ash constituents and nitrogen are taken by plants roots from soil. In such a way, the subject of this study is being relevant, for its purpose is the assessment of impact of water extract of various plants on laboratory germination of fine, fir and radish seeds. The main research methods of work are analysis, description and the experiment promoting a detailed subject development. As a result of the study we have found out the water extracts of deciduous trees and Cladonia sylvatica have positive impact on elongation of plants seeds. The present work has definite value for agro industrial complex, as far as the conducted researches allow defining term for germination of pine, fir and radish seeds under the influence of plants extracts.
