Abstract:
The occurrence of vesicular-arbuscular (VA) mycorrhizae in roots and Endogonaceous spores in rhizospheres of 180 host species belonging to 49 families from Swat Valley were investigated. VA mycorrhizae were generally present in all plants examined except members of Araeeae, Gymnospermeae. One to two members of Amaranthaceae, Chenopodiaceae, Compositae, Convolvulaceae, Cruciferae, Cucurbitaceae, Filicaceae, Labiatae, Leguminosae, Malvaceae, Poly-gonaceae, Rosaceae and Solanaceae were found to be nonmycorrhizal. The proportion of roots colonized by VA mycorrhizal fungi ranged between 50 to 100% in about half of the plants and 4-46% in the remaining plants. Spores of three species of Endogonaceae (Glomus macrocarpus var-macrocarpus, G. mosseae and Acaulospora laevis) were recorded from the soil samples. Spores of G. mossae were more abundant than the other species. Two to three types of fungal endophytes were observed in most of the roots examined..
