Phenological Stages of Development of Cornus L. S. Str. Species (Cornaceae) According to BBCH Scale

Under conditions of pronounced dynamic climate change, the scope phenological data is constantly expanding and increasingly extends beyond local regions. For international integration research, a standardized description stages plant development their identical coding used – BBCH scale (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie). Phenophases seasonal development, according to BBCH, are already unified for many different in origin, nature ecology, economic use plants common little-known species crops, including fruit. According scale, we described 23 cultivars Cornus mas L. selection gene pool M.M. Gryshko National Botanical Garden Academy Sciences Ukraine, genotypes C. officinalis Siebold & Zucc., nine sessilis Torr. ex Durand, as well three artificial hybrid from crossing × mas. Phenological monitoring was carried out NBG (Ukraine) two or times week seasons (2018–2020) beginning vegetation (bud development) November winter dormancy. In studied subgenus Cornus, some other stone fruit plants, there eight ten main development. all dogwood at growing season generative buds significantly ahead vegetative begin inflorescences flowering (principal growth stage 5 principal 6, respectively). Different varieties differ calendar dates onset duration certain major The obtained important further studies adaptive capabilities climatic conditions, practical genetic resources cultivars, introduction agricultural production, pharmacology, ornamental landscape gardens.
