We have examined Arbuscular Mycorrhizal (AM) fungal colonization in plants and compared AM fungal diversity in the open land and rubber plantation of Tripura, Northeast India. The AM hyphal colonization was highest observed in the roots of Cassia tora and lowest in Colocassia sp. Four and eight AM fungal species were extracted from the soil samples of rubber plantation and open land, respectively. Glomus, Funneliformis, and Ambispora were isolated from the soil samples. Glomus multiculae was highly abundant species isolated from both the sites. Diversity was more in open land than rubber plantation. The result reveals that the studied rubber plantation is poor in AM fungal diversity. [ABSTRACT FROM AUTHOR]

The article presents a study which examines colonization of Arbuscular Mycorrhizal (AM) fungi and diversity of Aquilaria malaccensis Lamk. (A. malaccensis) within herbaceous surroundings in Tripura, north-east India.It says that the samples of roots from several species of plants were collected from Syamalibazar area, in Agartala from August-December 2012. Results showed that the root samples from the tree with herbaceous plants surroundings revealed the presence of AM colonization.
