o:6949 Wood Fibre Characteristics of Pedunculate Oak (Quercus robur L.) Growing in Different Ecological Conditions Svojstva drvnih vlakanaca hrasta lužnjaka sa staništa različitih ekoloških uvjeta en Anatomical properties of pedunculate oak (Quercus robur L.) wood have not been previously investigated in Serbia, so bearing in mind economic-productive and ecological significance of this species, it was one of the main reasons why this research was conducted. In this paper, fibre length (FL), double cell-wall thickness (DCWT) and fibre lumen diameter (FLD) were measured in pedunculate oak wood from two different sites. The study was conducted at two sites (Donji Srem – MU „Raškovica-Smogvica” and Gornji Srem – MU „Kupinske grede”), situated along the Sava River and characterised by different ecological conditions, including flooding regimes. Measurements were conducted in radial direction, from pith to bark, in order to assess variation of investigated characteristics with cambial age, between two sites and between individual trees within each site. All measured characteristics from both sites increase going from pith to bark apart from FL in the area of Donji Srem – MU „Kupinske grede” that reaches maximum value in the central part of xylem and then decreases. Hydrological site conditions affect the dimensions of pedunculate oak wood fibres and these values are a bit higher in Gornji Srem – MU „Raškovica-Smogvica”, due to a greater quantity of available water. pedunculate oak (Quercus robur L.); fibre characteristics; Gornji Srem; Donji Srem; wood variation 1552101 0012-6772 1552102 https://www.drvnaindustrija.com/site/assets/files/3220/7_drv_ind_vol_73_3.pdf 1552099 https://doi.org/10.5552/drvind.2022.0023 2025-01-23T20:57:28.426Z 44 yes 46 Dušan Jokanović 46 Tatjana Ćirković-Mitrović 0000-0003-2620-1751 46 Vesna Nikolić-Jokanović 46 Radoslav Lozjanin 46 Iva Ištok application/pdf 762194 https://unilib.phaidrabg.rs/o:6949 no yes 16 70 92000001 2022 Drvna industrija 73 317 325 Faculty of Forestry and Wood Technology 2022
