Termite resistance ofKlainedoxa gabonensis(kruma), a tropical lesser-utilised-species for commercial utilisation

Abstract

The paper describes the testing for termite resistance of a lesser-utilised tropical species known as kruma (Klainedoxa gabonensis) in order to evaluate its potential for the building, construction and related wood-consuming industries. Results suggest that kruma heartwood can be rated as very durable and the sapwood as durable. It is concluded that utilisation of this wood species could reduce over dependence on traditional primary species.

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

“…The crystals in N. papaverifera exhibited a significant blunting effect on the saws and cutting instruments used to prepare the samples. The number and frequency of tyloses contribute to a reduction in wood's permeability to fluid flow, which limits moisture uptake and makes it resistant to pulping liquor and preservatives [19]. According to Dietsch, P., Franke, B., Gamper, A., & Winter, S. (2015) [20], their presence has an impact on water circulation in live trees.…”

Azadirachta indica (Neem Tree) for Furniture Production in Ghana: A Historical Review

“…However, about 90 % of the country's wood exports are covered by 10 species, and only 4 species contribute roughly 60 % of the total production. The lesser-used-species (LUS) occur in abundance in the forest, but increased harvesting must be on a sustainable basis to ensure continued harvesting potential (Antwi-Boasiako et al, 2017;Ewudzie et al, 2018;Nanang, 2010). Azadirachta indica (neem tree) is an evergreen tree widely distributed in the tropical forest in Ghana and belongs to the family Meliaceae (Mahogany) (see Figure 1).…”

“…The utilization of other LUS needs to be looked at as urgently as a possibility of increasing the wood resource base in the country. A successful expansion of the resource base is dependent on adequate knowledge of the properties of LUS (Antwi-Boasiako et al, 2017).…”

“…The wood is moderately heavy, stable and resembles mahogany. The working quality is like that of oak but has straight grains (Antwi-Boasiako et al, 2017;Hummel et al, 2016). These are factors that can lead to their use in furniture production.…”

“…Successful promotion and utilization of lesser-used species (LUS) will yield a relief and reduce demand on the few primary species. But the efficient utilization of the lesser-used wood species depends on knowledge of their physical and mechanical properties (Antwi-Boasiako et al, 2017;Chowdhury et al, 2017;Lumor et al, 2017). It is expected that the efficient utilization of the LUS would improve the sustainability of the tropical timber resources and reduce negative environmental impacts such as a reduction in biodiversity and desertification (Chowdhury et al, 2017).…”
