Summary: This study evaluated the genetic inheritance of growth traits, identified suitable deployment zones, and determined optimal triploid hybrids for different experimental sites. Significant clonal and site effects as well as clone-site interactions were observed for all growth and yield traits. The Weixian, Gaotang, and Yanzhou sites were suitable deployment zones, while Zhengzhou, Taiyuan, Pinggu, and Xiangfen sites were optimal for deployment. Yield performance and stability varied significantly among all triploid hybrids, highlighting the need for a suitable clone that performs well across all sites. The triploid hybrid clone S2 was identified as the ideal genotype based on both performance and stability.

Summary: The economic feasibility of different management strategies of hybrid aspen coppice stands in Northern Europe was compared in a study, which found that a 25-year rotation with different early thinning methods was more profitable at low discount rates, while short coppice cycles for only bioenergy production became more profitable at higher discount rates. Profitability of hybrid aspen coppice stands was confirmed, but focused bioenergy production carries more risks.

Summary: The study found that the maximum mean annual volume increment of hybrid aspen occurs at 25-30 years of age, with a mean diameter at breast height reaching 27-29 cm after 29-30 years. Clones ranked higher based on diameter in early trials also performed well in the final measurements 20 years later, suggesting that superior growth clones can be selected based on young trial results.

Summary: The study focused on the liquefaction of biomass to obtain bio-oil for chemical and energetic applications. The researchers used short rotation coppice (SRC) poplar cultivations and found high bio-oil yields ranging between 70.7 and 81.5%. The study also revealed correlations between the carbon content and higher heating value (HHV) in the bio-oil, indicating the potential for bio-oil to contribute to renewable energy and a greener global economy.

Summary: This study compares the potential of carbon sequestration and economic viability of poplar short rotation coppice systems under different irrigation conditions. The results show that restrictive irrigation due to climate change challenges the productivity and profitability of these plantations. Improving irrigation and promoting biomass utilization are important for short-to medium-term carbon sequestration.

Summary: This study extends the research on economically optimal carbon storage to mixed-species size-structured stands, using an ecological model and optimization methods to analyze carbon storage and timber revenues. The results show that carbon pricing can increase stand volume, promote tree species diversity, and lower the marginal cost of carbon storage with a higher number of tree species in a stand.

Summary: The presence of insect passages significantly increases the probability of stem rot in hybrid aspen, while a negative correlation is observed between rot and stem cracking. Genetic factors play a major role in determining the probability of stem rot in the study material, with potential for improving both productivity and rot resistance for different clones.

Summary: The main challenge in designing a cost-effective harvesting system for European short-rotation plantations is the small tree size. This challenge is further complicated by the need for 4-meter logs for high-end products, ruling out whole-tree chipping. A simple system involving mechanical felling, tractor skidding, and excavator operation has been proven capable of maintaining harvesting costs below 17 euros per green ton, with limited capital investment and versatility for alternative jobs.

Summary: The current interest in short-rotation coppice (SRC) of woody crops for bioenergy or bioproduct purposes has been revived due to the context of ecological transition and the fight against climate change. This study established plantations in five regions of Quebec, Canada to determine the growth and yield potential of different willow cultivars. After six years of cultivation at two coppicing frequencies, it was found that the productivity of tested cultivars did not differ significantly, except for Salix viminalis 5027. Overall, the high yields observed after several years indicate the production potential of willow crops in SRC for Eastern Canada.

Summary: The relationship between tree water use and biomass production, as well as the driving factors of transpiration, were studied in young Populus tomentosa trees under different water treatments. Results showed that irrigation significantly increased biomass production with only a small increase in water use, while deficit irrigation resulted in higher biomass production but with higher water consumption. Factors such as vapor pressure deficit and solar radiation were found to be major drivers of transpiration in P. tomentosa trees, while soil water content had minimal effect. These findings contribute to a better understanding of poplar water use characteristics and can aid in developing models for predicting biomass production.

Summary: The main goal of this review was to assess the potential of fast-growing tree species in agroforestry areas for biomass production in the Baltic Sea region. The study showed that short rotation forestry is the most suitable approach for managing these areas, with willows and poplars suitable for short rotation coppice and black alder suitable for energy wood plantations.

Summary: There has been no prior research on the range of sites, potential yield, and financial characteristics of poplar short rotation coppice plantations in Hungary. A model presented in this paper suggests that these plantations have the potential for profitable financial performance, with considerations for break-even points and wood chip prices. Industrial poplar plantations have longer rotation periods and higher returns, while short rotation coppice plantations offer more evenly distributed cash flow. Expanding the application of poplar short rotation coppice may require specific subsidies and an extension of the rotation cycle beyond the current 15 years limit.

Summary: Biomass plays a crucial role in renewable energy sources, and the recovery chain of residual biomass is of fundamental importance. Producing pellets from pruning residues of hazelnut and olive trees in Italy showed differences in bulk density, length, and metal concentrations between the two types of pellets. Quality parameters such as heating value, ash content, and metal concentrations varied between hazelnut and olive pellets.

Summary: The study compares the economic and environmental performance of alternative thinning method based on crop-tree management (AT) and traditional thinning from below typical of the shelterwood system (TT) in beech forests. The results show that AT has higher work productivity and lower costs compared to TT, but the reduction of GHG emissions is not as effective as in TT. Furthermore, the use of animals for extraction operations does not significantly improve the performance of AT. Overall, crop-tree management is a suitable option for beech forest stands, but further studies are needed to evaluate its impacts on the overall rotation cycle and productivity.
