Influence of environmental factors on agrobiological indexes of a grape of cultivar Odeskyi Chornyi

Abstract

The purpose. To study correlation between ecological conditions, modern state and areas of grape plantations using databases of a cadastre of vineyards and results of field experiment. Methods. Topographical (for assessment of space elements of land forms), cartographical (at formulation ampeloecological maps for selection ampeloecotopes), calculated. At study of influence of environmental factors on agrobiological indexes of a grape they determined amount of racemations for a scrub (pieces), productivity for a scrub (kg), percentage by weight of sugars and titrable acids in a grape (g/dcm3), average weight of a cluster of grapes (g). Results. Allocation is studied of areas of grape plantations on regions of Odessa oblast in the period of 1979-2015 by means of the manager of database of cadastre of vineyards Vin-Cad-Ukr. Conclusions. Results of probes confirm link between quality and amount of gained products with ecological conditions of terrain of growing of plantations and specify necessity of application of ecological investigations at solution of questions of their allocation.
