The Influence of Variety and Climatic Year on the Phenology of Blueberry Grown in the Banat Area, Romania

This paper’s aim was to investigate the influence of variety and climatic year on vegetation phenophases in blueberries grown southwest Romania, Banat region. study carried out during growing season 2020–2022 a blueberry plantation, for ‘Duke’, ‘Hannah’s Choice’ ‘Elliott’ varieties. In study, phenological traits were recorded using BBCH scale observation phenotypic data as Julian days. Thus, it is found that duration each phenophase characterized variety. The calendar periods onset spring development stages varieties have differed from depended weather conditions. case stage, depending variety, maximum amplitude 87 stage (75% blue fruits) 51 days, minimum amplitude, 25 (bud swell) 59 (late pink bud). coefficient variation, year, generative phenophases, had values between 6.5% (BBCH 67-petal fall) 21.1% 51-bud swell). It phenophases. results indicate cultivars demonstrated high degree plasticity respond gradual changes environmental conditions are important evaluation cultivar cultivation prospects studied area.
