Quantitative investigation of carbohydrates in the xylem of different species and clones of willows [Skirtingų rūšių ir klonų gluosnių medienos angliavandenių kiekybiniai tyrimai]. – Botanica Lithuanica, 9(4): 329–335

Qualitative and quantitative analysis of carbohydrates is an important indicator of the xylem quality, on which the possibilities of utilisation of plant raw material depend. Results of the investigation on quantity of carbohydrates in the xylem of certain willow (Salix) species, their hybrids, and clones, cultivated under unified conditions, are presented in this paper. Willows characterised by the largest quantity of cellulose, hemicellulose, and lignin are specified. Dependence of the quantity of carbohydrates in raw material upon species, hybrids, and clones, as well as the age of plants is analysed. Importance of carbohydrates for the quality of xylem is discussed.

Keywords: Salix, Salicaceae, cellulose, hemicellulose, lignin.
