Abstract:
... The International Poplar Commission, FAO UN, was appointed to serve as the International Cultivar Registration Authority for the genus Salix in 2013 (Kuzovkina and Vietto, 2014). Eight hundred and fifty-four cultivar epithets were included in the Checklist for Cultivars of Salix (Willow) to provide the baseline for the formal registration of new cultivars epithets (Kuzovkina, 2015a, 2015b). Twenty ...

Abstract:
... The development of eco-friendly connection material instead of steel is a challenging problem in timber structures. Following densification, the mechanical properties of low-density species can be significantly improved. Densified wood may be a potential connection material in timber structures. This paper reviewed the different processing for densified wood, and obtained favorable mechanical prop ...

Abstract:
... This study deals with the use of evapotranspiration and covering as a means of drying wood. The principle is based on the fact that tree species with outstanding sprouting capacities are able to leaf after being felled and are physiologically active as long as they have enough water. The course of wood drying (the stems) was examined in relation to their subsequent foliage creation and ongoing eva ...

Abstract:
... Mechanical felling is the most cost-effective solution for harvesting short-rotation poplar plantations, but the damage inflicted by conventional shear-cutting devices on tree stumps has raised concerns about stump mortality and resprouting vigor, both of which are crucial to coppice regeneration. To determine whether such concerns are justified, this experiment monitored the survival and resprout ...
