This publication presents a synthesis of research studies focusing on the various methods of argan tree (Sideroxylon spinosum L.) propagation. It is based on the PRISMA method (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), which is recognized for structuring and enhancing the transparency of systematic reviews and meta-analyses.
The literature search was conducted using the same keywords in the Scopus and Web of Science databases, selecting publications in English and French published between 2000 and 2024. Using the PRISMA method, 55 articles were selected, the majority of which (36) originate from Morocco, the native country of the argan tree.
The bibliometric analysis, performed using the VOSviewer software, enabled the visualization of links between the main keywords related to argan tree research. This map highlights the central position of germination, around which micropropagation, seed sowing, in vitro culture, and vegetative propagation are organized.
The discussion compares the different techniques: seed germination, which has a low success rate, is contrasted with the advantages of cutting and grafting, which allow for rapid rooting and greater genetic stability. In vitro micropropagation also appears to be a promising method, although it requires strict acclimatization conditions.
In conclusion, the study emphasizes the importance of combining traditional methods with modern biotechnological approaches to ensure the reproduction and sustainable conservation of this emblematic species.
