Shvets I. Darmera peltata (Torr. еx Benth.) Voss in the city of Kiev: morphology, reproductive biology and autecology

The thesis is dedicated to researching of morphological, reproductive and autecological characteristics of plant D. peltata to clarify aspects of their breeding, cultivation, using and distribution in conditions of Kyiv. The results of a systematic researchins of patterns of seasonal growth and development, morphogenesis and morphometry generative and vegetative organs of plants D. peltata are firstly presented. The phenological spectrum and the duration of growth and development of inflorescences, flowering, ripening fruit, growing season of plants and fenorytmotype have been built and set. The features of the reproductive biology of plants D. peltata are presented, technological methods generative and vegetative reproduction are improved, sown seed quality and features prehenerative period ontomorphogenese seedlings are defined. It was investigated winter resistance, frost resistance, heat resistance, drought resistance and gas resistance of plants D. peltata and assessed the overall adaptation. According to modified scale assessment conducted decorative of plants D. peltata and provided scientific and practical recommendations for their using in landscape gardening.
