The object of the research was the apricot trees Wonder Cot, Spring Blush, Magic Cot, Lilly Cot, Pinkcot, Perle Cot, Orange Red, Sweet Cot, Big Red, Kyoto, Faralia and Farbaly varieties, grafted on the rootstock Mirobalan 29C.

During the research we studied the period of onset of the phases beginning to bloom and the maturation of fruit harvest, the period between these two phases at various apricot varieties. It was established that the biological particularities of the variety influence the period of onset of the beginning of flowering phases and the maturation of apricot fruit harvest, the period between these two phases.
