Study of quantitative characteristics of three cultures (peonies, hostas, irises) for their use in urban landscaping

Abstract The purpose of this study is a scientifically based selection representatives the genera Paeonia L., Hosta L. and Iris promising for use in urban landscaping. choice research objects determined by three criteria. These are: 1) Paeonia, - large generic complexes with number cultivars; 2) their cultivars are characterized wide morphological diversity; 3) Russia, these cultures have long been actively used landscape design. Their own set characteristics has studied them. signs important plants greened city. genus represented sample 19 P. lactiflora Pall. Japanese flower shape. variability quantitative was length stem, its thickness at base diameter flower. 23 names. according to four width leaf blade, area, petiole. 10 six height plant, flowers on peduncle, flower, blade. Statistical processing obtained data carried out using program “Statistica Base”. Classical methods used. development models beds AutoCAD program. From total composition sample, varieties forms were selected each culture under study. In cultivar ‘Bu-Te’. For Hosta, ‘Frances Williams’ ‘Liberty’.
