Disponibilite de pollen performant pour la production de semences ameliorees de palmier a huile (Elaeis guineensis Jacq.)

Par : Langue : Fr Détails de publication : Abidjan; Plantations-Recherche-Developpemnt ; 1999Sujet(s) : Ressources en ligne : Abrégé : Oil palm seeds are taken from hybrids whose thin-shelled fruits are obtained by crossing thick-shelled palms with shelless palms. The latter, which are sterile females, are used as male parents. Male inflorescence formation is induced, amongst other things, by stress linked to production. Obtaining sufficient quantities of pollen is thus a major problem, which hinders the dissemination of the best varieties. Very severe pruning of shelless-pisifera-palms provided a greater understanding of inflorescence sex differentiation. Pollen production has since been quadrupled, and the planting material currently extended is more productive and more resistant to vascular wilt.
