Abstract

The Ivorian forest area has been declining because of his abuse. To reduce the negative impact of forest loss on natural resources, various reforestation projects are undertaken. The species used in these programs are usually rapidly growing exotic legumes. Unfortunately, these plants are very poorly adapted to the prevailing conditions and targets are rarely achieved. Hence, replacing them with native species should be considered. In order to meet this requirement, it would be necessary to select some taxa from the local flora with the same characteristics (such as high germination rate, rapid growth, etc.) and this study follows this pathway with research into the morphological characteristics and seed germination of two legumes (Dialium guineense and Distemonanthus benthamianus) and the survival rate of seedlings from germination. For this, fruits and seeds of these two species were collected, observed, described and put into germination. The results give 43.33% germination capacity among D. guineense and 67.77% in D. benthamianus when seeds do not undergo treatment. These rates can be improved by applying their specific treatments. A rate of 85% is obtained after scarification of the D. guineense seed. The rate of D. benthamianus increases to more than 88% after soaking in water. The different survival rates are estimated at over 80%. These plants may be used instead of exotics.
