Occurrence of Ecto- and Endo-mycorrhizae with the Roots of Casuarina Equisetifolia in Various Soil Types

Out ofthe fourteen samples collected from various locations in India, VA-mycorrhizal formation was observed in nine soil samples. External mycelial (ecto-mycorrhizae) association were also recorded in ten samples. Harting net and intercellular mycelial colonization with the ischolar_main under the situation were not observed. In few soil samples plant ischolar_mains were colonized with both endomycorrhizal and ecto-mycorrhizal fungi, whereas in five soil samples only endo-mycorrhiza and in three ecto-mycorrhiza alone was observed. Only in one soil sample no mycorrhizal association was noted study indicate the presence/absence of both type of mycorrhiza forming fungi in the soil. Maximum VAM ischolar_main colonization was observed in Jabalpur soil, indicating the presence of potent VAM fungal species. Higher ecto-mycorrhizal colonization was recorded in Baroda soil sample.
