Sažetak
Quality of four disease resistant table grape cultivars bred in Hungary (Lidi, Lilla, Palatina, Sarolta) was studied after storage in air at 0 °C for 4 weeks and one week at 21°C (simulated marketing period). Cultivar significantly affected all studied parameters (soluble solids concentration (SSC), titratable acidity (TA), SSC/TA ratio, electroconductivity (EC) and pH). However, storage affected only SSC and pH. Significant interaction between cultivar and storage was determined on SSC, EC and pH. Among studied cultivars, the most significant changes after storage were detected in Palatina (only TA remained unchanged) and Lidi remained practically unchanged (except in pH which decreased). Sensory analysis showed that significant differences among cultivars occurred in sugar/acid ratio, aroma, taste and general appearance. In spite of significant changes of quality parameters after storage, Palatina received the best marks from panelists. Future studies should be focused on optimizing postharvest technology for these resistant cultivars to preserve quality during storage.
