With the diminishing supply of softwoods, the focus on hardwoods will progressively increase. The wood industry might consider fast-growing hardwoods like poplar to enhance their wood supply. Nonetheless, many hardwood species exhibit limited durability when exposed to outdoor conditions. To ensure effective wood protection, it’s crucial to achieve uniform impregnation with preservatives. However, many hardwoods have uneven impregnation, reducing protection effectiveness. The underlying reason for this phenomenon has not yet been comprehensively investigated. Although it is known that numerous wood anatomical factors impact the transport of fluids (e.g., vessels (Cǒté, 1963), formation of tyloses (FOT) inside vessels (Kitin et al., 2010), tension wood (TW) (Tarmian and Perré, 2009), different types of pits (Wardrop and Davies, 1961), there is lack of
knowledge about which of these anatomical factors trigger the uneven distribution (Figure 2a). The formation of tension wood (FOTW) is known to occur particularly in fast-growing tree species (Cuenderlik et al., 1992). Trying to fill this gap, we present preliminary results of microscopic studies investigating the influence of tylosis and the formation of tension wood (FOTW).
