Abstract
The influence of the climate in northeastern Romania on the growth and fruiting characteristics of some sweet cherry cultivars during three consecutive years was investigated.
The aim of this paper is to determine the influence of climate on the growth and fruiting characteristics of the selected sweet cherry cultivars.
In 2019-2021, the phenological stages of five sweet cherry cultivars from the international and local assortment were observed (‘Kordia’, ‘Hudson’, ‘New Star’, ‘Cetățuia’ and ‘Mara’). Climatic conditions in the north-east of Romania were also monitored and the influence of temperatures from 2020 on the start of vegetation was observed. ‘Cetățuia’ and ‘Maria’ (10th March) were the first cultivars and ‘New Star’ was the last to start vegetation (30th March). Significant differences between cultivars were found in the biometric characteristics using average values of trunk cross-sectional area (TCSA), crown volume, and crown density.
Also, during the research, the garnishing of the ridges with the fruiting shoots and spurs were determined, identifying the predominant type.
High temperatures and heavy rainfall during the summer months resulted in vigorous growth and flower bud differentiation was delayed due to overlapping shoot growth, which was especially evident in ‘Cetățuia’ and ‘Hudson’ cultivars.
The yield obtained depended on the fertility of the cultivars.
In the biotope conditions and applied fruit growing technology, the average yield in kg tree-1 varied between 29.5 kg tree‑1 (‘Hudson’) and 19.9 kg tree‑1 (‘Cetățuia’).
