- Resumen:
- This study investigated the effect of growth media on the germination and early growth of Tetrapleura tetraptera (Shum and Thonn). This was assessed at the Forestry Nursery Federal University of Agriculture Makurdi, Benue State, Nigeria. Two hundred viable seeds were immersed in 50% sulphuric acid for 15mins. The seeds after pretreated were sown in five different media namely: Topsoil, sawdust, river sand, amixture of topsoil and riversand and a mixture of riversand and sawdust. Completely Randomized Design (CRD) was adopted for this experiment. Data were collected on percentage germination on daily basis for 4 weeks. Growth parameters involving seedling height, number of leaves, girth and leaf length at 2 weeks interval for 8 weeks were also recorded. Analysis of Variance (ANOVA) was used to analyze the data collected. Mean separation was carried out to test for significant different among parameter using Duncan’s Multiple Range Test (DMRT) to determine the suitable growth media. The result showed that germination percentage was significant as 5% level of probability (p>0.05) and the highest germination percentage of 80% was recorded in riversand+sawdust. The highest number of leaves was observed in topsoil (10.05), seedling height (7.88cm) in riversand and sawdust, girth (0.57cm) in topsoil and leaf length (4.71cm) in sawdust. In raising the seeds of Tetrapleura tetraptera, riversand and sawdust should be used. To encourage domestication and conservation of Tetrapleura tetraptera, topsoil, mixture of riversand and sawdust should be adopted, this will ensure the production of vigorous seedlings for plantation establishment
