The growth environment of the standard trees (heavy competition up to the first harvest, free growth afterwards) coupled with long rotations (>20 years) results in high quality logs for solid wood products. Early pruning should be applied to enhance wood quality. We propose a system for the ...

In the sunfleck area the mean value QII decreases linearly with tau with small values of the standard deviation. In the penumbra area agreement with experimental data is inferior to that in umbra and sunfleck areas. Inside the canopy, the sunfleck fractional area ks, fitted by a second ...
Moreover, stands under conversion constitute not only a greater carbon reservoir but also a more durable and stable one than that of coppices, since they consist of more vital trees, with better developmental tendency and better stem quality. Results indicate the potentiality of stands under ...

The development and application of a standard methodology for evaluating the energy and carbon budgets of biofuel production systems is described, with emphasis on wood fuel production from short rotation coppice. Five major tasks were involved: definition of the system boundary; estimation of energy ...
The tree length system (TLS) was applied in most cases, and in the study stands too. Pre-harvest stand data were obtained with standard mensuration techniques on eight randomly selected circular sample plots for every harvested area. Plot surface area was 314 m2. Stand characteristics are shown...
In the context of quantifying carbon sequestration, the coppice management system provides a trade-off between the substitution effect of wood as an energy source and forest C storage [3]. The changes in carbon storage capacity and forest stand dynamics due to coppice systems are of particular in...
All plots (mixed and pure) planted with the black locust provenance "Nagybudmry" were excluded from the final analysis, due to low quality of the nurslings and consequent high mortality of this provenance (>50%). The plantation was treated as a low-input system, i.e., no fertilizers ...
