Only Abstract
Afficher plus [+] Moins [-]The use of physiologically active substances with properties than regulate plant growth and development is an important way to mitigate the impact of drought. Zinc is an essential trace element for most crops. This element regulates the biosynthesis of vitamins as well as the metabolism of proteins, carbohydrates and phosphorus nutrients, it increases the content of ascorbic acid, chlorophyll, dry biomass and has the ability to increase plant resistance to extreme temperatures. Based on the major importance⋅ of zinc, the purpose of the research was to study the action of the new coordination compound of zinc (CCZn), with the formula {[Zn3(HL)2(H2O)6] (SO4)2 1.5dmf∙2.5H2O}n, in which H2L = 2.6-diacetilpyridine bis (izonicotinoylhydrazone). The tested coordination compound was synthesized and analyzed within the Institute of Chemistry of MSU. Experiences were performed under laboratory conditions, and the results of the study demonstrated at the initial stages of ontogenesis beneficial influence of the CCZn on the growth and development of maize seedlings in optimal conditions and moisture insufficiency.
