The appearance, size and taste of fruit are among the main indicators of quality and marketability. These characteristics are determined by the content and ratio of biochemical components, which are influenced by the biotic and abiotic factors involved in cultivation. Studies have shown that the dry matter content of Dmina fruits is independent of rootstocks and planting schemes. However, the sugar content was significantly higher in fruits grown on M.26 rootstock with a planting scheme of 4.0×1.0 m and significantly lower in fruits grown on M.9 rootstock with the same planting scheme: 11.3% and 9.8%, respectively. Titratable acids were found in fruits grown on rootstock M.9 with a planting scheme of 4.0×0.5 m. In addition to the influence of planting scheme and rootstock, weather conditions also affected the biochemical content of Dmina fruits. Cool nights during the initial growth and development period contributed to dry matter accumulation, but negatively affected sugar synthesis. The correlation coefficients for all rootstock variants were higher than 0.703 and 0.911, respectively. The content of titratable acids depended significantly on the average daily and night-time air temperatures in the month before harvesting; this dependence was indirect and the correlation coefficients were high in all variants with rootstocks.
