AB  - The evaluation of wood chemical composition is of the great importance for the optimal utilization of wood raw material. Certain application areas of wood and wood products are closely related to the chemistry of wood components. Variability of the chemical composition of wood is common for the same wood species and even inside the single tree. Such variations may have significant effects on the properties of related wood material. Hence, this work presents a detailed evaluation of chemical characteristics of juvenile (10 years) and mature wood samples (72 years) of the Narrow-leaved Ash. The samples were taken from the tree trunks at three different heights. The contents of cellulose and lignin were higher in the mature wood samples. The cellulose content decreased with the increase in height of the tree trunk, while the vertical position had no significant effect on the lignin content. The content of the extraneous material, dissolved in toluene-ethanol solution, was significantly lower in the samples of juvenile wood, and it decreased with the increase in height. However, the same samples had the higher content of ash and the extracts dissolved in hot water, in regard to the samples of mature wood.

AB  - Following the water regulation along the Danube river, the area of natural forests decreases and the vegetation is fragmented. The goal of the study was to survey the recent phytocenological characteristics of the region of the protected floodplain outside the dam. We surveyed three site types in poplar plantations near Novi Sad. In the poplar plantations phytocoenological releves were made. The elevation of the study plantations is between 75 and 76 m a.s.l. The most represented species on the ground layer are the species Dactylis glomerata, Urtica dioica and Rubus caesius identified on the humofluvisol. The most represented species on the sandy part of the fluvisol were Rubus caesius, Solidago serotina, Dactylis glomerata and Equisetum arvense. The loamy form of fluvisol occurs at an elevation of 75.50 m. The most numerous species on the loamy form of the fluvisol in the flooded region were Rubus caesius, Solidago serotina, Polygonum hydropiper, Dactylis glomerata and Urtica dioica. Based on the above data, we determined the differences between ground vegetation in the study areas and in the part of the alluvial plain affected by additional moisture by both floodwater and ground water.

AB  - U radu su prikazani rezultati istraživanja anatomske i hemijske građe bukve sa različitih staništa područja Južni Kučaj. Cilj ovog rada je da se na bazi podataka dobijenih istraživanjima u okviru projekta "Proizvodnja drveta za zadovoljenje narastajućih potreba tržišta visoke šume" dobije uvid u karakteristike kvaliteta drveta analizom drvnih vlakana. Rezultati istraživanja pokazuju da se uočava razlika u anatomskoj i hemijskoj građi drvnih vlakana bukve u zavisnosti od uticaja staništa (nadmorske visine).
AB  - The anatomic and chemical structure of beech was studied at different sites in the area of Južni Kučaj. The aim of this paper is, based on the study data within the project "Wood production for satisfying the increasing demands of the high forest market", to present the characteristics of wood quality based on the analysis of wood fibres. The study results show that there is a difference in anatomic and chemical structures of beechwood fibres depending on the site effects (elevation).
