Abstract:

The purpose of the work is to evaluate the possibility of using poplar and willow in mixed short rota­tion coppice plantations (SRC) for sustainable biomass production. Two experimental mixed SRC plantations of pop­lar and willow clones were established. Selected poplar and willow clones were alternated in two double-rows in plantation Dalovice and in one double-row in plantation Michovka. Following biometric parameters were measured (height, number of stems and stem diameter at 1.0 m). Biomass yields were assessed using the destructive method and potential yields were then calculated for compared variable (clone, mixture) as dry biomass per hectare per year (o.d.t./ha/y). From results on both sites we can conclude that poplar and willow clones with similar growth dynamics (esp. of height) should be selected for mixed SRC in aim to create homogenous plantation canopy. Though the best poplar-willow mixture (Populus ‘Max 4’-Salix ‘Tora’) had slightly lower yields than monoclonal plantations of same clones in plantation Michovka after 3 harvests in triennial rotation, factor of locality as well as clone had much higher influence on yield and survival of experimental plantation. From our results we can conclude that mixed poplar­willow SRC plantations of carefully selected clones/varieties can be alternative to monoclonal SRCs.
