Diversity of AM Fungi Population in Tea plantation of Sikkim and Exploring its Friendly Association with the Plant
Abstract
Tea rhizosphere is abode for several micro-biota - a few beneficial and some antagonistic, among these Arbuscular Mycorrhizal (AM) fungi is a most common beneficial microorganism. Tea plantation, Temi Tea Estate Sikkim, was explored for Arbuscular Mycorrhizal fungal association to know their diversity and also to incorporate their use in agrosystems. AM spore was isolated and identified, further screening of the root for VAM infection were also carried out and percent of infections is 70- 80%. The species found were mostly Glomus and is found to be most dominant species followed by Gigaspora, Acaulospora and Scutellospora. Glomus mosseae was selected for further study in relation to its effects on growth and development of plants. Inoculation of Glomus mosseae found to effective in the growth of the plants and to some extend disease control. Different growth parameters of plant like phosphate utilization by tea plants followed by some biochemical changes like phenol, protein, enzymes and catechins following treatments were determined and results were found to be positive for sustainable maintenance of tea plant health.
