The study and creation of new physiologically active substances – regulators of plant growth and development is of exceptional importance. It is known that trace elements take an active part in many vital processes occurring in plants at the molecular level, therefore, trace elements such as the metals cobalt and nickel were used in the synthesis of coordination compounds designed to stimulate plant growth. Studies on the establishment of the optimal concentration of solutions of the studied preparations for pre-sowing seed treatment, the study of their effect on seed germination and germination intensity were carried out in the Laboratory of Agrochemistry of the Institute of Agricultural Sciences of the Academy of Sciences of the Republic of Uzbekistan.
Laboratory studies conducted to study the effect of drugs on the germination and germination of cotton seeds have revealed the most promising compounds with a set of properties that regulate the growth and development of cotton seed plants. Two series of experiments were carried out: tests of nickel compounds, and in the second – cobalt. Data were obtained on the comparative characteristics of indicators in determining the effect of coordination nickel and cobalt compounds on the germination and germination of cotton seeds, as well as data characterizing the effect of the tested compounds on the average length and weight of seedlings. Based on laboratory experiments, the following compounds were selected:
Co(HCOO)2·CH3CONH2·CO(NH2)2; Co(HCOO)2·HCONH2·CO(NH2)2;
Ni(HCOO)2·CH3CONH2·CS(NH2)2; Ni (HCOO)2·HCONH2 ·CO(NH2)2 for determining long distances.
