The influence of differing in weather conditions, especially at the beginning and end of the growing season, on the timing of onset and duration of the main phenophases of the plant is analyzed. The objects of the study were 4 varieties of different genetic and ecological-geographical origin of foreign selection: Brazos, Jumbo, Thornfree and Karaka Black. Phenological observations were carried out according to the classical methodology developed for this crop in Russia. The timing of all phenophases was significantly dependent on the temperature conditions of the growing season: in the year with a higher sum of average daily temperatures, the corresponding phenophases occurred earlier. According to preliminary data, the climatic indicators of the vegetation period of this region allow for the cultivation of blackberries of the main morphological groups (erect, semi-erect, trailing) and different ripening periods.展开更多
