Seasonal variations of arbuscular mycorrhizal fungal association with Ipomoea pes-caprae of coastal sand dunes, Southern India.

摘要

Two years seasonal studies on arbuscular mycorrhizal (AM) fungi associated with Ipomoea pes-caprae established on the coastal sand dunes of the west coast of India yielded 41 species belonging to six genera. The percent root colonizaion by the AM fungi was least during monsoon (28.7-64.6/100) and highest during post-monsoon (80.6-93.6/100), but the mean spore density in rhizosphere was least during post-monsoon (9.5-35/100g) and highest during summer season (58.2-132.5/100 g).
