The paper introduces aspects about the influence of environmental factors in 2019 – 2021 period on vegetative parameters of some sour cherry cvs. Analysing the time window between April and July (for each of the three years of study), 2019 and 2020 recorded a precipitations deficit of -71.6 mm (2019) and -86.0 mm (in 2020) in comparison with 270.0 mm representing the multiannual sum for this period, while 2021 recorded normal quantities of precipitations of 272.0 mm. The values of the trunk’s section area based on the average of three years of study were between 4.6 cm2 (ʹErdi Ipariʹ cv.) and 16.3 cm2 (ʹErdi Biborʹ cv.). The highest values for the volume of the crown were recorded in ʹDukatʹ (3.23 m3/tree) and ʹErdi Kordiʹ (2.88 m3/tree) cvs. while the lowest values were recorded in ʹErdi Biborʹ (2.19 m3/tree), ʹErdi Ipariʹ (1.56 m3/tree) and ʹErdi Kedvesʹ (1.55 m3/tree) cvs. The density of the trees’ crown had values between 4.74 cm2/m3 (ʹErdi Ipariʹ cv.) and 12.13 cm2/m3 (ʹErdi Kedvesʹ cv.). The estimates of the young shoots per tree and their average length over the three years of study have shown values superior than control for ʹErdi Biborʹ (41 young shoots with 70.5 cm), ʹErdi Kordiʹ (32 young shoots with 63 cm) and ʹDukatʹ (18 young shoots with 85.4 cm) cvs.
