Abstract
The objective of this work was to study the mycorrhizal status of Eryngium maritimum in the mobile dunes of Mehdia coastal area depending on the depth level reached by the roots. The obtained results showed that all the roots were mycorrhizal, different fungal structures were observed (arbuscules, vesicles, hyphae, spores and endophytic). However, the identified mycorrhizal parameters varied from the surface to the depth reached by the roots. The mycorrhizal frequency reached 88% by the depth. The highest mycorrhizal intensity (26.4%) was recorded at a depth of 53.05 to 73.05 cm. The highest arbuscular contents (22.72%) and vesicular content (11.80%) were recorded respectively at depths of 53.05 to 73.05 cm and 33.05 to 53.05 cm. The spores density in the rhizosphere of E. maritimum varied between 10 to 20 spores / 100 g of soil. Similarly, 19 spore’s morphotypes were isolated from five different genera: Gigaspora, Acaulospora, Entrophospora, Scutellospora and Glomus.
Among these morphotypes, ten species of endomycorrhizal fungi were determined: Glomus badium, Glomus aggregatum, Glomus multiforum, Gigaspora sp., Glomus invermaium, Glomus geosporum, Glomus glomerulatum, Glomus albidum, Glomus enticatum, Scutellospora verrucosa, Scutellospora calospora, Scutellospora heterogama, Acaulospora colaussica, Entrophospora infrequens. Mycorrhization of E.maritimum roots in depth, with development of exchange structures (arbuscular) probably facilitated the installation of this species, which grows well in the mobile dunes.
Key words: Morocco, Mehdia, mobile dunes, Eryngium maritimum, roots, depth, mycorrhizal status.
