Résumé
No mycorrhizae on Schoenoplectus maritimus in the Camargue. — It has been thought for a long time that wetland plants were devoid of mycorrhizae. In recent years, however, an increasing number of studies have reported the presence of vesicular-arbuscular mycorrhizae (or endomycorrhizae) on several marsh plants. These fungi are often beneficial for their hosts enhancing growth through better mineral and water nutrition as well as photosynthetic activity. Giving the importance of endomycorrhizae on resource allocation, we sought to determine whether these structures were present on S. maritimus growing in southern France. We sampled roots of 25 tubers collected at 5 sampling stations in 2 marshes for a total of 250 roots. Roots were stained and observed under a light microscope (400 X). No fungal structures (hyphae, vesicles, arbuscles, or spores) were observed on S. maritimus roots.
