Amélioration du taux de multiplication in vitro de Jatropha curcas L. ; Improvement of the rate of in vitro multiplication of Jatropha curcas L.

peer reviewed ; In order to improve the in vitro multiplication rate (number of shoots/explant/subculture) of Jatropha curcas L. axillary nodes taken from young plants of two accessions of this species (originating from Cameroon and Senegal) have been cultivated for three weeks on a MS medium supplemented with 8,87 µM BAP, 4.92 µM IBA, and 30 g.l-1 sucrose at pH 5.7±0.1, and solidified with 0.7% agar. The shoots obtained from each original explant were then transferred to proliferation media (PM) consisting of MS medium supplemented with 2.21 to 8.9 µM BA or 2.21 to 8.9 µM kinetin in combinati...
