| Abstract: | Three provenances of Khaya senegalensis saplings was observed once a week from early January 2008 to late July 2009.The results showed that cold tolerance,height growth and diameter growth and the fast growing period are significantly different among provenances.Overall,K.senegalensis saplings shooting 4 to 7 times per year,January to February is dormant period,April to September is the fast growing period of height,February and August to November is fast growing period of diameter. |
