Sažetak
Cherry (Prunus avium L.) is an economically highly profitable fruit crop, due to the market, technological and commercial value of the fruit. The aim of this paper was to determine how treatment with different physiologically active substances affects individual morphological properties of the cherry fruit, Regina variety. Research of the effect physiologically active substances had on 75 trees in the cherry orchard was conducted in 2022, during the phenophase of fruit growth and development, in two locations in Zadar County: Ninski stanovi and Murvica. The treatment was carried out three times, with knapsack sprayers on five variants in 3 repetitions: K - no treatment, only water, T1 - CaO 15%, T2 - biostimulator (based on Ascophyllum nodosum L. extract), T3 - prolin, T4 - salicylic acid. The first treatment was carried out at a certain time interval after full flowering, depending on the microclimate of the particular location, while the other treatments were conducted with intervals of 10 days. The fruit samples on which morphological measurements were performed contained twenty random fruits per repetition. Data processing with one-way analysis of variance (ANOVA) and regression test (Tukey) determined the effect of physiologically active substances on the length, width, weight, as well as on the percentage of dry matter and fruit toughness, by treatments and locations. The highest values of fruit length, width and mass were achieved by treatments T2 and T4, while the least cracked fruits were obtained with treatment T1.
