The topicality of using the sensory analysis of berries in enological practice at planning of agrotechnical complex at vineyard to receive the certain style and quality of production was grounded. For study of the influence of agrotechnical methods on sensory characteristics of technical sorts of grape Zagrey and Fragrant, selected by NSC “IVaW named after V.E. Tairov” (Ukraine), there was elaborated the algorithm of research, including field experiment and laboratory sensory analysis. The method of organoleptic analysis of berries, consisted of 20 parameters for assessment of visual, tactile and gustatory properties of pulp, peel and seeds, was approbated. Mathematical processing of experimental data was carried out by the methods of one- and two-factor analysis of variance and analysis of main components in the environment of package of applied programs MS Excell 2010, Statistica Statsoft ver. 7. 0 (Tulsa, USA). The sensory descriptors, characterizing the quality of studied sorts of grape, were determined. It was established, that agrotechnical methods of planting grape bushes influenced the sensory characteristics of berries of studied sorts.

The purpose. To study energy balance ampelocoenosis and to tap their efficiency. Methods. Field, laboratory and energy-balance. Probes were carried out in 2013-2015 on technical cultivars of grape Rubin Tairovskiy, Suholimanskiy belyi and Odesskiy chornyi. Results. On the basis of credit and debit part of energy balance effectiveness ratio of absorbed and general physiologically active radiation of ampelocoenosis with different structure of plantation and architecture of plants is determined. Conclusions. The method of energy balance enables to study experimentally magnitude of entering solar radiation, its absorbtion by leaves and sowings in separate spectral ranges, real photosynthesis and other processes. In the long term this method can be used in probes of production process of plants of grape and development of modern agrotechniques.
