Brovko O. Juniperus sabina L. at urbolandscapes of Kyiv (state of assimilation, autecology, analysis of phytocompositions)

The dissertation is devoted to the investigations of morphological, physiological, ecological, phytomeliorative pecularities for the typical forms of Juniperus sabina L. and their cultivars in the urbolandscapes of Kyiv. It's described a taxonomic characteristics, nutural range and form diversity of species, bioecological characteristics of perspective cultivars for using in greening. It has been determined that J. sabina for the level on reproductive development in the urbolandscapes of Kyiv belongs to the group of introductions which in during reproductive period producers the nonviable nonviable seeds and eco-environmental conditions receiving horticultural materials by the rooted cutting characterized. The dynamics of content of basic macronutrients elements and pigments of plastids has been researched in the needles of J. sabina and his cultivars, and also intensity of transpiration, dynamics of the water regime, intensity of photosynthesis and breathing. The features of spatial distribution over-ground and underground biomass of typical forms of J. sabina in monocenosis has been found out. Phytomelioration influence of this typical forms of J. sabina on water-physical properties and biological potency of the anthropogenic-destructive soils development of microflora's rhizoshere is shown. It is recommended for constructing of specific composition of urboculturphytocenosis with participation of J. sabina 30 cultivars of coniferous species, 22 kinds and forms of high-decorative broad-leaved species and shrub species and also 44 kinds and sorts of decorative and florescens blossom grassy plants in park and garden objects.
