标题:Population survey of Milicia excelsa, Pouteria adolfi-fridercii, Antiaris toxicaria and Prunus africana in south and south-western Ethiopia: implications for domesticating and establishing Seed Production Areas
摘要:The population dynamics and genetic qualities of stem height and dbh of the populations of Milicia excelsa##Pouteria adolfi-fridercii##Antiaris toxicaria and Prunus africana were assessed and studied in 14 forest ecosystems in south and south-western Ethiopia. A systematic random quadrat sampling technique was employed to identify potential habitat area for selected timber species in south and south-western Ethiopia. So##a total of 10 parallel transect lines were set out across each forest habitat. Milicia excelsa was assessed in four forest ecosystems; Bebeka -Duduka natural forest (45 tree stem ha-1) and Yayu coffee mixed forest (40 tree stem ha-1) appeared to have relatively denser population of M. excelsa compared to the other pilot forests. Similarly##statistically larger stem height (m) is observed in Bebeka-Duduka natural forest (x̅=29.5##SD=4.2) and larger dbh size (cm) in Bebeka 1 coffee mixed forest (x̅=48.5##SD=25.2) at p.
