Abstract
The ecological characteristics of M. altissima in Benin were studied within the sacred groves of Adakplamè, its exclusive environment in Benin. The data collected in 40 rectangular plots of 1000 m² sized showed that M. altissima is more preferred species in this environment (Ri = 37.5%). Variables such as tree density, stand basal area, and mean diameter of tree were respectively 20 stems/ha, 0.88 m²/ha and 23.91 cm. Weibull 3-parameters distribution showed an « inverted J » shape with the predominance of medium class-sized individuals (DBH=15 cm). Germination test showed that M. altissima seeds were affected by a tegumentary dormancy making the germination rate decrease after a long conservation. Soaking of seeds in boiling water was an appropriate treatment to overcome this dormancy and to reduce the latency time and the average duration of germination. This also speed up seeds germination and allowed the highest germination rates. Mass propagation by cuttings showed a weak performance of regeneration. Naphthalene Acetic Acid (NAA) and cuttings diameter showed no significant effect on the regeneration of M. altissima cuttings.
