Variability in wood properties of promising willow clones

The objective of the article is to investigate the variability in growth and wood properties of the willow clones. The growth and wood traits of four year old 21 clones willow clones were investigated. Analysis of variance showed that willow clones differed significantly for all the studied growth and wood traits. Among the growth parameters the maximum heritability value was shown by height wh...

Content of Carbon, Hydrogen and Sulphur in Biomass of Some Shrub Willow Species

Carbon, hydrogen and sulphur were determined in biomass (shoots and roots) of five species of shrub willow: Salix viminalis, Salix dasyclados, Salix triandra, Salix purpurea and Salix alba. Samples of the biomass collected from a strict experiment were dried to constant weight at 105oC. The content of carbon, hydrogen and sulphur was determined in an automatic determinator ELTRA CHS 500. In add...
