Вплив мікродобрив та імуномоделюючих препаратів на лабораторну схожість насіння

Abstract

А bility of seeds to germinate in an environment of high concentration is of great practical importance. Knowledge of seeds ability to germinate in a certain concentration of soil solution can solve the problem of exact seeding rate of particular crop.The results of studies of effect different concentrations of micronutrients of natural acids Avatar-1 carboxylates and immunomodulators (growth stimulant) Iodis-consentrate and Iodis-consentrate + Se on energy of germination and laboratory germination of seeds of cereal crops are presented. Sowing qualities of spring crops (wheat, barley) and winter crops (wheat, triticale) of cereal crops were determined according to the methods of DSTU 4138-2002 in the laboratory Quality of Seeds and Planting Material of Plant Growing Department of the National University of Life and Environmental Sciences of Ukraine.Higher rates of germination energy and laboratory germination of seeds of winter grain cereals were provided by application for pre-sowing treatment of immunostimulants Jodis-consentrate and Jodis-consentrate+ Se.Micro-fertilizer of carboxylates of natural acids Avatar-1 has a positive effect on seeds germination of winter grain cereals.A higher concentration of an aqueous solution leads to suppression of seeds germination of winter grain crops, whereas barley effectively uses water of solutions of increased concentration. Durum wheat, due to high protein content in the grain, germinates more slowly than soft wheat and requires a lower concentration of solution for germination than the soft.
