Leaf nitrogen distribution pattern was studied four times during the growing season in a 2-year-old Salix viminalis L. and Salix dasyclados Wimm. plantation in Estonia. We measured the vertical distributions of leaf nitrogen concentration, dry mass, leaf area and light environment (as fractional transmission of diffuse irradiance, a(d)) in the canopy. The light-independent nitrogen pool was eva...

Context Empirical studies of intraspecific genetic diversity and population structure can inform the evolutionary demographic history individual species landscapes at bioregional level. Aims We aimed to assess variation macroevolutionary microevolutionary temporal scales for Mirbelia viminalis, a key present on Hamersley Range in ancient highly diverse landscape Pilbara bioregion northwest West...

BACKGROUND Short rotation coppice willow is a potential lignocellulosic feedstock in the United Kingdom and elsewhere; however, research on optimising willow specifically for bioethanol production has started developing only recently. We have used the feedstock Salix viminalis × Salix schwerinii cultivar 'Olof' in a three-month pot experiment with the aim of modifying cell wall composition and ...

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...

We established linear and exponential relationships between leaf area (A) and leaf length (L), leaf width (W), W(2), L(2) and LW, in Salix viminalis L. Most relationships were significantly nonlinear, but good fits were obtained with both linear and exponential models. The nonlinear relationship between A and LW differed for leaves from sylleptic and proleptic shoots. Leaves from sylleptic and ...

The paper presents the impact of varied fertilisation with sewage sludge on concentration cadmium and copper in willow organs during first three years cultivation. lowest mean Salix viminalis biomass was found plantation fertilised only mineral fertilisers. content plants fertilisers higher than this metal grown non-fertilised soil by 23.4%. It has been shown that method does not have an alloca...
