Characterization of density and selected anatomical features of stemwood and branchwood of E. cylindricum, E. angolense and K. ivorensis from natural forests in Ghana

Variations of Stem and Branch Wood Properties of <i>Nesogordonia papaverifera</i> in Ghana

“…With increased density, the rupture modulus increases. This is in line with Dadzie, P. K., Amoah, M., and Ebanyenle, E., Frimpong-Mensah, K., (2018) [2] previous conclusion that wood strength is proportional to wood density. The heartwood had greater (729 kgm -3 ) and statistically significant basic density values than their sapwood (700 kgm -3 ) counterparts in terms of radial variation (Table 1).…”

“…The discrepancies could be attributed to the heartwood's higher extractive deposits than the sapwood, as well as the xylem maturation process. According to Dadzie, P. K., Amoah, M., and Ebanyenle, E., Frimpong-Mensah, K., (2018) [2] when wood transforms from sapwood to heartwood, its density normally increases. Similarly, the stem-heart (728 kgm -3 ) had a greater basic density than the stem-sap (698 kgm -3 ), and the branch-heart (730 kgm -3 ) had a higher basic density than the branch-sap (712 kgm -3 ).…”

“…Branchwood is a valuable wood resource with a variety of uses; it accounts for 25-32 % of total wood volume and is a secondary resource with high-value applications such as chaise lounges, wall and floor mosaics, garden arbors, dining stools, beds, garment racks, curtain rods, and many others that have yet to be fully explored [1]. Increasing market demand, both locally and globally, has resulted in overexploitation of most 'traditional' market species, with some becoming endangered (such as Milicia excelsa, Entandrophragma cylindricum, Khaya ivorensis, and others) [2]. Manufacturers and producers have little choice but to pay attention to the branchwood of known and lesser-known species that were previously disregarded if they are to stay in business as prices of traditional timber rise and quality and quantity diminish [3].…”

Response of vessel features to witches’‐broom disease in Zizyphus Jujuba branches

“…It should be noted that the means of vessel features measured here were collected from branchwood of the Z. Jujuba trees, and the values differed greatly to that from trunkwood studied by Zhu et al., (2015) with large average vessel size. Some studies reported that the sample position in a tree affected the vessel features of the tree (Dadzie et al., 2018; Kotowska et al., 2015; Zhao et al., 2019; Zhao, et al., 2019). In this case, the variation of vessel features would be discussed later following the description of branch level impacts.…”

Anatomical features of branchwood and stemwood of Betula costata Trautv. from natural secondary forests in China

“…Branchwood utilization in wood industries is limited by its small size and unknown wood properties. Special focus has recently been placed on branchwood to meet the increasing industrial demands and environmental pressures because of the decline in stemwood resources (Leitch and Miller 2017;Dadzie et al 2018). Branchwood can be engineered into a number of products, such as lumber (Okai and Boateng 2007), kraft pulp (Boyle and Ek 1972), and scrimber (Yu et al 2015).…”
