The study of the characteristics of the secondary flowering of Cerasus subhirtella 'Autumnalis'.

ABSTRACT: The short flowering period of ornamental cherry trees is the main factor limiting their use in gardens. Determining the secondary flowering characteristics of ornamental cherry trees is required to prolong their flowering period. In this experiment, Cerasus subhirtella 'Autumnalis' was used as the experimental material. The phenological differences in their annual growth cycle were observed using the BBCH coding system. The cooling requirements of the flower buds were evaluated by the chilling hours model (temperature between 0 and 7.2 °C) and the Utah model. The expression of the core gene involved in bud dormancy regulation DAM (dormancy-associated MADS-box) from the completion of flower bud differentiation in one year until the following year was measured by performing rea
