Pryplavko S. Dependence of some physiologycal processes and productivity of agricultural cultures upon the influence of metalliferous synthetic regulators of growth of plants

The research object is a winter wheat of Mironovskaya 67 and Polesskaya 90 sorts, sugar beet of Nosovskiy sort and of hybrid Juvileynyi; metal-complex compounds on the basis of urotropin (hexamethylenmine). The object of research is to determine dependence of separate physiological processes under the influence of the new metalliferous regulators of growth of plants and to give the guidance of their application for the crops of winter wheat and sugar beet in the conditions of South Poliss'ya in Ukraine. Research methods are: the field, laboratory, physiology-biochemical, laboratory-chemical, mathematically-statistic, calculated-comparative ones. Theoretical and practical results are complexes on the basis of urotropin (hexamethylenmine), dimethyl sulfoxide and salts of cobalt (preparation Slavutych), manganese (preparation Crystalin) or barium (preparation Oksamyt) which increase field germination, multiply the area of leaf surface and total content of chlorofyll in the leaves of plants of winter wheat and sugar beet. Preparations Slavutych and Kristalin depending on forecrops and methods of application can substantially increase the productivity and quality of winter wheat corn. Application of preparations Slavutych, Kristalin and Oksamyt promote increase of the firmness of the plants of sugar beet against diseases and also the productivity and saccharinity of root crops both during encrustation of seed and additional processing of vegetative plants. Preparations Slavutych, Kristalin and Oksamyt can be used as elements of technology of growing of the other agricultural cultures. The novelty is in the firts received research data of the growth regulating and fungistatic action of 18 synthetic metal-complex compounds on the basis of urotropin and dependence of their activity upon their structure. The auxin, cytokhynin, retardant and fungistatic effect of the investigated metal-complexes was determined by means of specific biotests. It is exposed that the ion of metal, ligand surroundings and concentrationinfluence on the activity of the investigated complexes. It is shown that the most active stimulators of the stem and root of sprouts growth of agricultural cultures are manganese, cobalt and barium complexes. The extant of application: the systematic recommendations for the use of investigated preparations for sowing of winter wheat and sugar beet are developed. The recommended norm for processing of winter wheat seed is 10 g/t and for sprinklings of sowing in the phase of forming a tube - 10 g/ga. For processing of sugar beet seed the recommended norm is 5 g/2,5-3 sowing units and for sprinkling of such sowing - 20 g/ga in the phase of ajoining of leaves in a row or in row-spacing.
