Abstract - Opuntia ficus-indica, known as prickly pear, is the most important plant species in the Cactaceae family. It is known as a multipurpose use plant with great worldwide interest because of his ecological and socioeconomic virtues such as the combat against erosion and desertification. In prickly pear multiplication by somatic embryogenesis was very important as a first step to induce mutation from suspected fertilized ovules. In this study, our interest has been oriented to identify the origin of somatic embryogenesis initiation. For this purpose, morphological study linked to anatomical investigation, made in the early stages of induction revealed that the tissue involved in this callogenesis was none other than the cambial section of vascular bundle of the funicular tissue.

Keywords: Opuntia ficus indica; Somatic embryogenesis; Ovular Tissue; Anatomical studies.
