Inventaire et Analyse de la phytodiversité végétale de la région de Ghardaïa (Cas de Metlili et Noumérat).

Abstract

Our work is dedicated to the evaluation and analysis of plant phytodiversity in the Ghardaïa region (Noumérat, Metlili), by carrying out a floristic study, physical and chemical analyzes of the soil, as well as a histological study of the tissues of certain selected plant species. The results obtained showed that the soil in our study area is alkaline with very low salinity and a sandy texture. It also showed that organic matter is poor and humidity is low. As well as the total and active limestone content varies from one station to another. The inventory that we carried out made it possible to cite a list composed of (25) species divided into (15) families, noting that the biological type Therophyte is very widespread in the two stations.
