“…In addition, our study showed the dominance of the genus Diversispora, followed by the genus Glomus. This last is in line with previous work on the argan tree (Sellal et al, 2017), on the olive tree , and on citrus plants (Artib et al, 2017), which also showed that the genus Glomus was the most dominant. According to Stutz et al (2000), the representatives of this genus are the most adapted to fluctuations in environmental conditions.…”

In Morocco, Tetraclinis articulata is one of the species of great socio-economic value. Improving the resistance and survival of thuya to sometimes extreme environmental conditions is a concern of managers. For this, the use of arbuscular mycorrhizal fungi can promote the good growth of this species. We aim to study the effect of a native endomycorrhizal inoculum on the growth of T. articulata plants under nursery conditions. Our results showed that after eighteen months of inoculation, there was a significant effect on the growth of the mycorrhizal plants as compared to the non-mycorrhizal plants. Concerning the root fresh weight (8.58 g), the root system length (34 cm), the collar diameter (5.44 mm), and the number of branches (27) of the mycorrhizal plants are higher than those observed in the non-mycorrhizal plants, 7.67 g, 30 cm, 4.13 mm, and 24, respectively. However, the results of the height and the fresh weight of the shoot part of the non-mycorrhizal plant are superior to those observed in the mycorrhizal plants. The number of spores formed in the rhizosphere of plants inoculated was 135/100 g of soil. And they were represented by 29 endomycorrhizal species belonging to ten different genera: Glomus (6 species), Acaulospora (8 species), Rhizophagus (3 species), Diversispora (1 species), Funneliformis (3 species), Septoglomus (2 species), Scutellospora (2 species), Claroideoglomus (1 species), Entrophospora (1 species) and Gigaspora (2 species). Diversispora versiformis is the most abundant species; its frequency of occurrence reached 30%. The results of this inoculation study highlight the importance of native endomycorrhizal fungi isolated from the rhizosphere of Aderj in increasing the root system and improving the growth of T. articulata plants.

“…These results are similar to those of Sellal et al (2017), who also revealed the presence of 29 species from spores isolated from the soil of argan plants inoculated with an endomycorrhizal inoculum in the nursery. Similarly, Artib et al (2017) were able to identify 23 species in the rhizosphere of inoculated Citrus aurantium L.…”
