The paper characterizes poplar (Populus alba, P. nig­ra) and white willow (Salix alba) forests of the Irtysh and the Black Irtysh river floodplain, together with the silvery salt tree (Halimodendron halodendron) community of the Black Irtysh river floodplain. The Black Irtysh floodplain willow and poplar forests are separated into a new alliance, Rubio dolichophyllae—Populion albae Taran all. nov. (Salicetalia purpureae Moor 1958, Salicetea purpureae Moor 1958), which includes the associations Rubio dolichophyllae—Popu­letum albae Taran 1997 and Rubio dolichophyllae—Salicetum albae Taran ass. nov. The Halimodendron halodendron community is probably related to the class Nerio-Tamaricetea Br.-Bl. et de Bolós 1958. White poplar forests in the Irtysh R. upper reaches, described within the Semipalatinsk city limits, belong to the association Heracleo dissecti—Populetum albae Taran 1997 and its subassociation H. d. —P. a. lamietosum albi Taran 1997 (Equiseto hyemalis—Populion nigrae Taran 1997, Salicetalia purpureae Moor 1958).

The presence of UDP-D-glucose 4-epimerase (EC 5.1.3.2) in the culture tissue of white poplar was evidenced. As found, the partially purified enzyme preparation contained UDP-D-glucose glucosyltransferase, UDP-D-galactose galactosyltransferase and non-specific enzymes able to cleave the uridine-diphosphate saccharides into the appropriate hexose monophosphates. The activity change of UDP-D-glucose 4-epimerase in tissue culture cells during the growth was in accord with changes in D-galactose content in cell walls and indicated the possibility to regulate the formation of polysaccharides containing D-galactose at the level of production of UDP-D-galactose in cells.

White poplar nursery production is mainly based on vegetative propagation hardwood cuttings. In this study the reaction of three clones of white poplar (Populus alba L.) on term of cuttings' preparation and planting according to parameters of survival and growth of rooted cuttings in three nurseries in Northern part of Serbia. There were two terms of cuttings' preparation and planting examined: a) mid-March and d) the beginning of April (standard term). Obtained results suggest considerable differences between nurseries and between examined terms. Differences between clones were not significant, but there were found significant effects of interactions of factor Clone with other two main sources of variation. The best results were obtained by cuttings that were prepared and planted in mid-March, due to faster growth and survival of rooted cuttings. The positive effect of the earlier term is evident particularly in clones L-12 and L-80 and enable feasible production of rooted cuttings of these clones, especially in nurseries that obtained better conditions. Results obtained in this study suggest that influence of terms of cuttings' production and planting is important issue concerning introduction of clones with relatively poor rooting capacity, optimization of nursery technology of experimental white poplar clones, and improvement of white poplar nursery production in general.

Forested Area

White poplar is a native stand-forming tree species in Hungary, covering 3.1 per cent of the forested area. More than 70 per cent of the white poplar stands can be found on calcareous sandy sites in the Danube—Tisza region, so they play a significant role in the poplar management of this part of the country. The most important task ahead of Hungarian poplar growers is to improve the quality of poplar stands and plantations based on selecting new clones and cultivars. The growth and yield of four promising white poplar clones was evaluated on a marginal site in central Hungary. The clones `1-1 425-4' (Populus alba x Populus alba), and 11 758' (Populus alba Mosonmagyaróvár 124) seem to be suitable for wood production, while the 427-3' (Populus alba x Populus alba cv. Bolleana) and 422-9' (Populus alba x Populus grandidentata) clones (with decorative stem form) could be better used for tree lines and ornamental plantations.

Selection Of

The creation of modern green spaces should be based on the selection of a sustainable assortment. Resistance is evaluated on the basis of a number of physiological indicators. Preliminary testing is of particular value for industrial regions with difficult climatic conditions. The purpose of this study was to study the resistance of 4 species of poplars to drought, winter conditions, the effects of diseases and pests, and atmospheric pollution. Resistance assessment was carried out for the species Populus alba, Populus balsamifera, Populus canadensis, Populus nigra, covering the period from 2015 to 2019. The results of visual observations showed that all species of poplars have high winter resistance — 4–5 points. Maximum winter resistance is noted for white poplar, minimum — for canadian poplar. The gas stability of poplars is estimated at 3–5 points. The greatest stability is noted in balsamic poplar, the minimum — in canadian poplar. Drought resistance among poplar species is estimated at 3–4 points. White and canadian poplar showed the least resistance to drought, while canadian poplar showed the maximum. Estimated scores of resistance to diseases and pests were 4–5 points, the highest indicators were noted for balsamic poplar, the minimum — for black poplar. On the basis of the identified indicators, the directions of poplar use in green construction are proposed.
