Abstract

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.
