The plant collections of the NDP “Sofiyivka” of NAS of Ukraine including accessions of the subtribe Malinae Rev., formerly the subfamily Maloideae C. Weber (Rosaceae Juss.), are the objects for research in the field of plant introduction and phytodiversity protection. Because of the significant number of park’s holiday-makers, which are not always careful about plants, the posttraumatic regenerative ability of plants is of particular importance for adaptation and periods of the highest regenerative activity could be favourable for vegetative reproduction, including microcloning. Thus, Malinae of the “Sofiyivka” might be useful for germplasm conservation and utilization in the breeding programs.
Intr0ducti0n. Green plantations in Ukraine require optimization of species, shape and varietal composition of ornamental plants. These include the genus Cotinus Mill. one of the oldest genera of angiosperms of the Sumac family (Anacardiaceae Lindl.). Matcrials and mcth0ds. The species and varietal composition of the Cotinus collection of the Sofiyivka National Dendrological Park of the National Academy of Sciences of Ukraine was studied. Morphological fea- tures of collectibles of the genus Cotinus were studied according to generally accepted methods. Rcsults and discussi0n. In he collection of the National Arboretum “Sofiyivka” of the National Academy of Sciences of Ukraine two species and 4 cultivars of the genus Cotinus were tested and studied, namely: C. obovatus Raf., C. coggygria Scop., C. coggygria ‘Royal Purple’, C. coggygria ‘Purpureus’, C. coggygria ‘Young Lady, C. coggygria ‘Golden Spirit’. According to our research, all members of the genus Cotinus winter-, frost-resistant, as well as drought-resistant plants. They have satisfactory growth and bloom and bear fruit annually. C0nclusi0ns. Thus, the collection of plants of NDP “Sofiyivka” includes a valuable fund of genetic resources of the genus Cotinus, which is used mainly as a mother plant for the reproduction of ornamental forms that are in demand in the market of seedlings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
