Abstract
Extractives and ash contents, share of latewood and annual rings width were analyzed in wood at different heights and different zones of the Pinus sylvestris L. stem cross-section. Additionally, the high performance liquid chromatography (HPLC) with a conductometric detector was applied to determine the sulphate (SO42−) and hydrogen phosphate (HPO42−) anions concentrations in wood and bark of Pinus sylvestris L. stem. Our results showed that the higher share of latewood in annual rings the lower ash and extractives contents in the wood, but the higher sulphate (SO42−) and hydrogen phosphate (HPO42−) anions concentration. The sulphate (SO42−) and hydrogen phosphate (HPO42−) anions concentrations in the bark of the Pinus sylvestris L. stem were higher at the top than at the butt-end part.
