Appraisal of Natural Durability of a Lesser – Known Boscia anguistifolia (A. Rich) Wood Using Ground Contact Test
The optimal utilization of lesser-known wood species is dependent on their natural durability. In this study, the natural durability of a lesser-known wood species (Boscia anguistifolia) using ground contact test was carried out. Wood blocks of Boscia anguistifolia and Ceiba petandra (reference species) with dimensions of 20 x 20 x 300 mm were obtained from the axial and radial direction of the trees. The wood blocks were conditioned and their moisture content determined before exposure to ground contact for 12 weeks after which their weight loss was determined. Data obtained were analysed using analysis of variance (ANOVA) at 0.05 probability level. The moisture content of B. anguistifolia and C. petandra ranged from 12.80 – 18.02 % and 12.73- 16.63%, respectively while the weight loss of B. anguistifolia and C. petandra ranged from 5.10 – 69.11% and 37 – 50 % respectively along the axial position. It was observed that the core wood in the base portion of B. anguistifolia has the lowest weight loss value of 5.10% while the reference species has a value of 39.73%. Conclusively, B. anguistifolia is moderately durable at the base part of the species when compared with the reference non-durable species used in this study.
