The growth and metal uptake of two willow clones (Salix fragilis 'Belgisch Rood' and Salix viminalis 'Aage') was evaluated in a greenhouse pot experiment with six sediment-derived soils with increasing field Cd levels (0.9-41.4 mg kg-1). Metal concentrations of eight elements were measured in roots, stems and leaves and correlated to total and soil water metal concentrations. Dry weight root bi...

Nordh, N.-E. 2005 Long term changes in stand structure and biomass production in short rotation willow coppice. Doctor’s dissertation. ISSN 1652-6880, ISBN 91-576-6919-8. Short rotation willow coppice (SRWC) is a recently commercialised agricultural crop in Sweden, producing biomass for energy. The expected lifespan of a SRWC plantation is more than 20 years, or at least 5 harvests. Consequentl...

Background and Purpose: Most projections of the global energy use predict that biomass will be an important component of primary energy sources in the coming decades. Short rotation plantations have the potential to become an important source of renewable energy in Europe because of the high biomass yields, a good combustion quality as solid fuel, ecological advantages and comparatively low bio...

1. Host-plant genetic variation affects the diversity and composition of associated above and belowground communities. Most evidence supporting this view is derived from studies 3 within a single common garden, thereby constraining the range of biotic and abiotic environmental conditions that might directly or indirectly (via phenotypic plasticity) affect communities. If natural variability in ...

the cecidomyiid species rabdophaga heterobia (loew) induces gall on willow's male catkins, and causes small rosettes at the extremities of shoots and swollen lateral buds or lateral rosettes on some species of willow. during the years 2006-2007, a study on willow pests in the west azarbaijan province (saatloo poplar research station) was conducted. the following nine willow species were us...
