The assessment of pomological parameters in sour cherry trees (Prunus cerasus L.) under the conditions from the N-E of Romania

Abstract

The paper presents aspects about the influence of the environment factors between 2018-2020 on growth and fructification in sour cherry cultivars. In 2018 (530.5 mm), 2019 (415.0 mm) and 2020 (245.2 mm in the first seven months of the year), the quantities recorded were below the multiannual limit (562.6 mm). The largest surface of the trunk was recorded for Erdi Bibor (14.8 cm2) with positively significant distinct difference in comparison with the variants average (8.9 cm2), while the smallest surface was for Erdi Ipari (3.7 cm2) with negatively significant distinct difference. The highest number of twigs was recorded for the Rival (41.5 cm) and Erdi Kedves (47.7 cm) cultivars. The average weight and equatorial diameter of the fruit was between 2.9 g with 16.1 mm for the Stelar cultivar and 6.3 g with 22.4 mm for the Erdi Bibor cultivar.
