Incidence of arbuscular mycorrhizae in some liverworts of Jammu & Kashmir, India.

摘要

Thalli and soil samples of 20 liverwort and hornwort taxa belonging to three orders, i.e., Metzgeriales, Marchantiales and Anthocerotales collected from an altitudinal range of 305-2580 m were studied for Arbuscular Mycorrhizal (AM) colonization and spore populations. AM fungi were associated with ten out of twenty (50%) taxa studied. Fungus colonized rhizoids, ventral scales as well as thallus. Mycorrhizal colonization frequency was observed to be more in smooth-walled rhizoids as compared to tuberculated ones in all invaded taxa. Spores of nine species of AM fungi were isolated from the rhizosphere soil of invaded hepatics.
