Abstract

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.
有柄栎树的木材纤维特性不同生态条件下的生长
有花序栎树(Quercus robur L.)木材的解剖特性在塞尔维亚尚未进行过研究,因此考虑到该树种的经济生产和生态意义,这是进行本研究的主要原因之一。本文测定了两个不同产地有梗栎树木材的纤维长度(FL)、双细胞壁厚度(DCWT)和纤维腔直径(FLD)。该研究在两个地点进行(Donji Srem - MU“Raškovica-Smogvica”和Gornji Srem - MU“Kupinske grede”),位于萨瓦河沿岸,具有不同的生态条件,包括洪水状况。在径向方向上进行了测量,从髓到树皮,以评估所调查特征随形成层年龄的变化,在两个站点之间以及每个站点内单个树木之间。两个地点的实测特征均呈从髓到皮的递增趋势,但东吉栎木的“库宾斯克等级”在木质部中部达到最大值后减小。水文场地条件影响有梗橡木木材纤维的尺寸,由于可用水量较大,这些值在Gornji Srem - MU“Raškovica-Smogvica”中略高。
