FLOWERING PHENOPHASE OF SOME APRICOT („P. armeniaca L.“) CULTIVARS DEPENDING ON AIR TEMPERATURE

Abstract

The paper presents the three-year results of the effect of basic climatic parameters on the flowering of 12 apricot cultivars in conditions of Čačak. The significant differences in the beginning, progression and duration of flowering among years were determined. The beginning of flowering in 2020 was on March 12, in 2021 on March 1, and in 2022 on March 24. Flowering phenophase in one cultivar lasted between 6 and 9 days in 2022 and between 8 and 16 days in 2021. Differences in the beginning of flowering among cultivars were more pronounced in years with earlier flowering date.
