Abstract

Trešnja je gospodarski značajna kultura na području Mediterana. Zbog utjecaja biotskih i abiotskih čimbenika osjetljiva je na raspucavanju ploda. Problematika pucanja plodova trešnje jedan je od glavnih problema u proizvodnji trešnje. U ovom istraživanju prikazani su rezultati istraživanja raspucavanja plodova kod 17 sorti trešnje uzgajanih na lokaciji Ninski Stanovi u sjevernoj Dalmaciji. U istraživanju su praćeni kvalitativni parametri (tvrdoća, šećeri, kiseline, omjer kiselina i šećera , promjer). Praćenje raspucavanja provedeno je u svibnju i lipnju 2019. godine. Iz dobivenih rezultata vidljivo je da različite sorte različito reagiraju na raspucavanje plodova ovisno o više kvalitativnih parametara. Sorta 'Volovsko Srce' pokazala se kao najotpornija sorta sa 6% raspucalih plodova dok je 'Early Biggi' sa 72% imao najviše raspucalih plodova. Omjer tvrdoće ploda kreće u rasponu od 1,09 do 2,82 kg cm-2. Najveći promjer ploda, postotak šećera i ukupnih kiselina utvrđen je kod sorte 'Sweet Valina'. Na osnovi dobivenih rezultata ne može se tvrditi da će sorte koje su u istraživanju istraživane tekuće godine prošle bez pucanja plodova biti otporne na pucanje i sljedeće godine, a još manje može biti sigurno da će to biti i u nekom drugom uzgojnom području pa zbog toga bi trebalo nastaviti istraživanja i u narednim godinama.

Abstract (english)

Cherry is an economically important crop in the Mediterranean area. Due to affect of biotic and abiotic factors it is sensitive on fruits cracking. The problem of cherry fruits cracking is one of the main problems in cherry production. This study presents the results of a cracking of 17 cherry cultivars at the Ninski Stanovi location in northern Dalmatia. Qualitative parameters (hardness, sugars, acids, ratio of sugars and acids, diameter) were monitored in the research. Monitoring of the crack was proven in May and June 2019. From the obtained results, it is visible that different reactions on fruits cracking were sorted differently, regardless of several qualitative parameters. Cultivar ‘Ox Heart’ proved to be the most resistant variety with 6% of cracked fruits, while 'Early Biggi' with 72% had the most cracked fruits. The fruit hardness ratio ranges from 1.09 to 2.82 kg cm-2. The largest diameter of the fruit, the percentage of sugar and total acids was determined in ‘Sweet Valina’ cultivar.
Based on the obtained results, it cannot be determined that those cultivars that were resistant to cracking in the current year without cracking the fruit next year will be sorted, and even less can it be certain that it will be in another breeding area, so research should continue in the coming years.
