The vegetative propagation of oleander (Apocynaceae), an ornamental plant for aesthetic use, is based on the technique of cuttings. This study focused on optimizing this multiplication. To do this, two types of matrix were used, in particular soil and water. Cuttings were taken from oleander plants and the apical, middle and basal parts of the stems were cultured in water and soil. The results showed that after 3 weeks the cuttings, thus installed, constitute the seat of the formation of the roots and the new-formation of the buds. The characteristics of these cuttings were established with cuttings from plantations obtained by artificial regeneration. Thus, on a stem twig, we distinguished basal, middle and apical cuttings. Recovery time varies from one category of cuttings to another, but the highest recovery rate (86.7%) was obtained with middle cuttings. The results obtained are of paramount importance in the success of the rapid multiplication of this ornamental species highly prized by urban florists in Niger.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
