Five morphological and quantitative characteristics of one-year old seedlings of red oak (Quercus rubra L.), black walnut (Juglans nigra L.), wild pear (Pyrus pyraster Borkh.) and birch (Betula verrucosa Ehrh.) were studied. The seedlings were produced and cultivated in the controlled conditions of the nursery in the region of Jastrebac (Serbia, Serbia&Montenegro), by the classical method - standard preparation of plots, fertilization, watering, protection against insects, plant diseases and weeds. Above-ground seedling height, root collar diameter, root length, number of secondary roots and the leaf assimilation area were analysed. Intraspecific and interspecific variability of morphological traits of the above species were assessed by the comparative analysis and statistical methods.
