Abstract:
In this paper the wood physical (dry matter content % and basic density g· cm-3) and energetic (higher heating value J·g-1) characteristics of new poplar and willow clones selected for SRC are reported. Replicated samples of wood have been collected in field: stem disks of different diameter with about 10 cm of height. The samples, were weighed in distilled water for volume determination, oven dried to constant weight and milled for the determination of calorific value with a calorimeter. Interesting differences were found between species, clones and cultural model but also along the stem of the tree. Generally new poplar and willow clones show higher specific density if compared with traditional ones, respectively from 0.34 to 0.39 g·cm-3 compared with 0.29 to 0.32 g·cm-3. Willows clones show values similar to poplar for dry matter content and basic density, respectively about 48-50% and 0.38-0.39 g·cm-3. No statistically significant differences were observed for the calorific values of the clones tested. The 5-year SRC model allow to produce wood with different characteristics if compared with 2-year SRC model. Variations along the stem are difficult to evaluate, they depend mainly on species/clones..
