Author(s): Muhammad Nafees, Sami Ullah, Tanvir Burni
Abstract: Mycorrhizal study were conducted on the adventitious roots of six pteridophytes collected from different localities of District Buner. All plants were found heavily mycorrhizal. Apart from the marked dimorphism in external and internal hyphal elements, arbuscules and vesicles were noted which support the presence of multiple infections. Maximum Vesicular Arbuscular Mycorrhizal (VAM) infection were observed in the adventitious roots of Pteridium aquilinum (98%) and minimum VAM infection in Asplenium dalhosia (82%) and Adiantum capillus (82%). From the rhizosphere of plants, three VAM genera spores Glomus spp, Sclerocystis spp and Gigaspora spp were collected. All the fungal spores were studies for different micromophological features such as shape, color, wall, dimension, inner content, hyphae and presence or absence of septa. Plant species had a significant role in root tissue colonization by Mycorrhizal fungi.
