Multiplication végétative de ximenia americana l. par drageonnage

In the Guinean savannah Highlands of Cameroon, X.americana L. is an important socio-economic species facing high zoo-anthropic pressure. The objective of the study is to characterize the natural and artificial suckering of the species. An inventory has been realized in March 2011 in 20 square plots...
