Sažetak
Cultivation of sweet cherry (Prunus avium L.) is spread across the Republic of Croatia, but its importance is greater in the Mediterranean region, especially for early ripening cultivars. Extreme weather conditions during flowering and ripening negatively affect the commercial of fruits. Aim of this work was to determine the occurrence of sweet cherry fruit cracking and fruit firmness and to examine it with the amount of precipitation during fruit development. Research was conducted during 2019 and 2020 at the sweet cherry orchard in Ninski Stanovi, Zadar County. Fruits were harvested at commercial maturity. Fruit cracking index (CI) and fruit firmness (FF) of fifteen sweet cherry cultivars ('Burlat', 'Cristalina', 'Early Burlat', 'Ferrovia', 'Germersdorf', 'Giorgia', 'Grace Star', 'Lapins', 'Regina', 'Samba', 'Summit', 'Sunburst', 'Sweet Early', 'Sweet Valina' and 'Volovsko srce') were evaluated. Statistical comparison of fruits was made by oneway analysis of variance and Tukey post hoc test. Person correlation between CI and FF of all cultivars and both years was also carried out. Significant differences were found for CI and FF between the cultivars. Furthermore, the influence of the year on the measured parameters is also visible. 'Grace Star' has shown the lowest CI value in 2019 (2.80), while ‘Sweet Early’ in 2020 has shown the highest CI (52.4). FF ranged from 1.09 kg/cm2 in 'Early Burlat' in 2019 to 2.82 kg/cm2 in 'Volovsko srce' in same year. There is a moderate negative correlation between the CI and FF. Obtained results are useful for the selection and valorization of sweet cherry cultivars for the Mediterranean growing area in the Republic of Croatia. Conducted research contributes to the assessment of extreme weather conditions risk, mostly precipitation, which could affect the cracking and firmness of sweet cherry fruits.
