Study describes Arbuscular Mycorrhiza (AM) fungi colonization within the roots of cultivated tea plants (Camellia sinensis) at four sites, that is, Goodrich, Archadia, IIP, and Vasant Vihar of Doon Valley, Dehradun, India, from April, 2008, to March, 2009. Microscopic study of sterilized and stained root segments showed presence of four species namely Glomus fasciculatum, G. mosseae, Gigaspora margarita, and Acaulospora scrobiculata belonging to three genera of mycorrhizal fungi. Maximum AM colonization was observed during April–September and minimum was observed for December-January months of the year. Comparative study of AM fungi colonization at four sites during rainy season showed maximum colonization (100%) at Archadia site having soil with high organic matter, less acidity, and low phosphorus (P) whereas minimum (64.59%) at IIP with low organic matter, more acidity, and high P content. However, no variation in nitrogen content was observed at all four sites. Study suggested a positive relation of percentage root colonization with soil organic matter and negative relation with acidity and P content of soil. Study concludes that the percentage AM colonization is the function of seasonal variation in physicochemical properties of soil and presence of AM inoculums in the soil at a particular time.
