Abstract

Mycorrhizal colonization of different agroforestry tree species in two social forestry nurseries was investigated. Percentage of Arbuscular mycorrhizal (AM) infection, number of resting spores and AM fungi species varies both in tree species as well as in two different nurseries. This variation is attributed to various factors such as mycorrhizal status and other management practices. In both nurseries, Glomus species dominated in all tree species followed by Sclerocystic, Gigaspora, Acaulospora, Scutellospora and Entrophospora. Interestingly, Azadirachta indica and Terminalia catappa have shown maximum and minimum infection respectively in both nurseries. Certainly, mycorrhizae could contribute substantially to achieve better results.

Key words: Arbuscular mycorrhizal fungi, agroforestry tree species.
