Abstract

Mycorrhiza is known for its growth enhancement effect on plants. They are also important in soil ecology, such as protection of host plant against pathogens, soil stabilization and many more. This study was conducted to investigate the diversity of vesicular arbuscular mycorrhiza (V AM) in association with Azadirachta excelsa in two different habitats (natural stand and planted trees). Wet-sieving and decanting method was used, and identification was done based on the characteristics of spores. The natural stand exhibited a higher value for species richness and Shannon-Wiener index, at 11 and 1.8607 respectively. While for planted trees, the values were 9 and 0.9537, respectively. The natural stand also showed a higher value for evenness, which was 0.776 compared to that of the planted trees at 0.434. However, the planted trees outnumbered the natural stand in spore density per 100g of soil at 3503 spores while the natural stand was only 2221 spores. Both study sites had moderate degree of similarity. Twelve species were identified with three species each from Acaulospora, Gigaspora, Glomus and Scutellospora. Among the species, Glomus sp. 1 was the most abundant in species found in both study sites. Results of the study showed that A. excelsa grown in the natural forest exhibited a more diverse biodiversity compared to planted trees.
