Wood Fibre Characteristics of Pedunculate Oak (Quercus Robur L.) Growing in Different Ecological Conditions

Anatomical properties of pedunculate oak (Quercus robur L.) wood have not been previously investigated in Serbia, so bearing mind economic-productive and ecological significance this species, it was one the main reasons why research conducted. In paper, fibre length (FL), double cell-wall thickness (DCWT) lumen diameter (FLD) were measured from two different sites. The study conducted at sites (Donji Srem – MU „Raškovica-Smogvica” Gornji „Kupinske grede”), situated along Sava River characterised by conditions, including flooding regimes. Measurements radial direction, pith to bark, order assess variation characteristics with cambial age, between individual trees within each site. All both increase going bark apart FL area Donji grede” that reaches maximum value central part xylem then decreases. Hydrological site conditions affect dimensions fibres these values are a bit higher „Raškovica-Smogvica”, due greater quantity available water.
