Leshchenko O. Lolium perenne L.: varieties, plant adaptation, cultural phytocoenosis

The thesis presents the results of ecological characteristics and adaptive potential of plants Lolium perenne L. of five varieties of Ukrainian breeding on morphological, anatomical, physiological, biochemical levels and features of their usage for creating cultural phytocoenosis. Firstly provided a comprehensive assessment of autecology features of plants varieties 'Adriana-80', 'Leta', 'Lytvynivskyy-1', 'Orion', 'Svyatoshynskyy' and experimentally revealed the presence of variety specific by anatomical and morphological characteristics of vegetative organs of plants Ukrainian selection, which can serve as markers for plant resistance to adverse of ecofactors. Determined stimulated action of nanoscale molecular structured water clusters to crop seeds quality varieties of Ukrainian breeding.Established that the content of flavonoids, phenols and reduced glutathione in vegetative organs of plants can be served as the determining criteria for the distributionrange of grades for their usage. The practical recommendations of the usage plant varieties Lolium perenne for creating lawn in a city was elaborate.
