EFFECT OF A NEW COMPLEX OF TRACE ELEMENTS MICROCOM-V ON SOME METABOLIC PROCESSES AND PRODUCTIVITY OF VITIS VINIFERA L

The first local complex compound of trace elements Microcom-VA dedicated for grape has been tested in field conditions on 4 cultivars in comparison with two iron containing compounds ? FeSO4 and Dissolvin. The results of foliar treatment of vine, which were obtained in the 4 - year experiments (modification of content of photosynthetic pigments, microelements in the tissue, phosphor components and carbohydrates compounds, optimization of shoots growth and maturation, grape quality and quantity, winter resistance), let to assume, that complex of trace elements Microcom-VA led to optimization of plant nutrition, improving grape and wine quality, fuller realization of genetically based potential of frost and winter resistance.
