Fedak V. Physiological features of fatty acids accumulation by Zea maize plants affected by growth regulators and soil fertilizers

The thesis was devoted to research of physiological and biochemical features of the fatty acid total lipids content, nonetherified and anionic forms of fatty acids in leaves and the corn accumulation, chlorophyll accumulation in leaves, fat in grain accumulation of maize plants hybrid Zbruch throughout vegetation, depending on soil fertilization and plant growth regulators Zeastymulin. For the first time carried out research dynamics of the fatty acid total lipids content, nonetherified and anionic forms of fatty acids in leaves and corn in different phases of vegetation depending on fertilization and Zeastymulin. It was established that in leaves during of vegetation content of fatty acids total lipids increased, bath in generative phase of development - decreased. Application of fertilizer and Zeastymulin increased their contents. Content nonetherified fatty acids in leaves of Zea maize plants under the fertilizers influence decreased and under Zeastymulin influence - increased. Application of fertilizer increased the accumulation of anionic forms fatty acids in leaves and of Zeastymulin - reduced. Application of fertilizers and Zeastymulin led to growing of fatty acids total lipids content during corn maturation. By influence of fertilizers contents nonetherified forms of fatty acids in corn of Zea maize plants decreased, by the influence of Zeastymulin - increased. Content of anionic forms fatty acids during corn maturation gradually increased, decreased affected by Zeastymulin and increased - by the influence for fertilization. Plant growth regulator Zeastymulin and fertilizers lead to accumulation in leaves Zea maize plants chlorophyll. By actions fertilizer corn productivity increased by 17 %, under the influence Zeastymulin 12 %. By influence of fertilization fat content in corn increased by 14 %, under the influence Zeastymulin - 20 %. The total content fatty acids increased by 16 % under the fertilization influence and 21 % - by Zeastymulin.
