Performance - Light saturation curve for photosynthesis is determined by the genetics of grapevine genotypes, through the physiological element - the degree of penetration of leaves by solar radiation, photosynthesis intensity, leaf structure, physiological state of plants, influence of ecological factors, etc. It results of the diurnal phytonomonitoring are exposed to different genotypes of grapevines under the influence of green operations, in the conditions of the drought of 2020. The research undertaken established the moment of initiation and gradual increase of the performance up to the level of solar radiation of 1,000 micromol/m2*s. The essential optimization is maintained between the parameters of the solar radiation of 1000-1500, the saturation at the level of the solar radiation of 1,400 and the stopping of the performance reaches the level of the solar radiation of 1,800 micromol/m2*s.
