Biological peculiarities of growth and development of highbush blueberry (Vaccinium corymbosum L.) mother plants in the conditions of the right-bank forest-steppe of Ukraine

North American varieties of highbush blueberrry (Vaccinium corymbosum L.) were introduced in the Right-Bank Forest-Steppe of Ukraine for the first time and phenological peculiarities of their growth and development were studied. The terms of passing through phenological stages of the seasonal cycle of growth and development of mother plants of the introduced highbush blueberry varieties in the conditions of the Right-Bank Forest-Steppe of Ukraine were considered. The optimal period for propagation of the studied highbush blueberry varieties by green, semi-legnified and legnified cuttings was determined. This term coincides with the period of the most intensive shoot growth (June-middle of July) and for gathering legnified cuttings it is the period of deep dormancy (October-November). It was established that the researched varieties are characterized by high vegetative productivity which is the biological foundation for vegetative propagation.

Key words: Highbush blueberry, varieties, phenological stages of plant development, mother plants, stem cuttings.
