- Abstract
The arid lands are the most disturbed and degraded, mainly because of the wind, water shortage, and salinization. With the loss of vegetation and loss of productive surface soil as primary factors. In these areas, the protection and regeneration of degraded lands are critical for sustainable agriculture, and dryland ecosystem's enhancement. Mycorrhizal fungi take up a substantial portion of soil rhizosphere microflora and play an essential role in plant development. In this context, a study of mycorrhizal spores isolated from the date palm rhizosphere located in the Zagora palm groves (Moroccan desert) was conducted. The collected soil samples were analyzed for chemical and physical properties and spores were separated from the soil and examined. Root colonization, spore density, abundance, and morphological studies, were the considered parameters. The mean frequencies and intensities of colonization were 98% and 73% respectively. The maximum spore density was at 34,165 spores / 20 g of soil, and the lowest was at 22,015 spores / 20g according to the site. Twenty-eight arbuscular mycorrhizal fungi species belonging to seven genera were identified in all the sites studied. These endomycorrhizal were significantly similar in the four different soil samples. The "Zagora" inoculum contains a mixture of the mycorrhizal spores previously mentioned.
