The Adaptability of Some Sweet Cherry Cutivars With High Agro-Productive Potential in the Climatic Conditions in Iasi County

Abstract

The biological properties of the sweet cherry (Prunus avium L.), as well as the physico-chemical characteristics of the fruit were studied for 3 years within RSFG Iași (2018-2020). The investigations were carried out at the Sârca Research Base on six varieties of sweet cherries. These included following the phenological stages (flowering period and fruit ripening period), but also the particularities of the fruit in terms of physical characteristics and biochemical composition. The highest weight of the fruit was recorded in 2020 in the ‘Regina’ cultivar. ‘Regina’ is characterized by an average flowering period, lasting between April 11th and 28th. The earliest cultivar both in terms of flowering and fruit ripening is the ‘Golia’ cultivar. All other varieties have an average fruit ripening period (June 15th-30th). The soluble dry matter content was between 11.29 (‘Hudson’) and 18.61 (‘Maria’). The researches carried out and the results obtained show that the studied varieties presented good results of adaptability in the pedoclimatic conditions in the area of Romania.
