ABSTRACT: Khaya senegalensis is one of the largest and most majestic trees in Africa. Overexploited
for its precious wood and medicinal values, the natural stands of this species
are in danger of extinction in Cote d’Ivoire. Its sustainable management
through regeneration techniques and assessment of its degree of adaptation to
the changing climate is necessary. The aim of
this study is to evaluate the effect of different environments on
seedling germination and development in Khaya
senegalensis. A total of 2160 seeds from different mother plants
and 540 individuals from seed germination were selected and evaluated. The
trials were conducted on three sites that were distinct by their microclimate
(two nurseries in Cote d’Ivoire and one greenhouse in France). Analysis of
variance showed that germination and morphology parameters were not influenced
by the characteristics of the mother plants used (p > 0.05), but rather by
the study sites (P Khaya senegalensis. This study could be
extended to other species in order to restore disturbed ecosystems.
