Abstract
Arbuscular mycorrhizal (AM) fungal association in Sandal (Santalum album) natural stands in different parts of the Kerala State was studied. AM fungal root colonization in Sandal trees was low and ranged from 5 to 18%. AM fungal spore density was also low and ranged from 56 to 85/10 g soil. Glomalean fungal community in Sandal rhizosphere soils comprised of five genera (Glomus, Acaulospora, Gigaspora, Scutellospora, Entrophospora) with a total of 35 species. Mycorrhization of Sandal seedlings with Glomus fasciculatum, G. mosseae and Acaulospora appendicula showed marked difference in seedling biomass (dry wt.) than untreated control. Highest percentage of mycorrhizal inoculation effect (MIE) of 51.4% was recorded in G. fasciculatum + A. appendicula treatment.
