Growth and Productivity of AM Inoculated Tropical Tree Seedlings

Abstract

Container grown seedlings of tropical trees such as Acacia leucophloea, A. mangium, A. nilotica, Delonic regia, Derris indica and Tamarindus indica were inoculated with three arbuscular mycorrhizal fungi (AMF) viz. Glomus fasiculatum, G. mosseae and Gigaspora margarita. The growth responses ortbe seedlings such as height, root eo1lar diameter, root and shoot biomass were analysed. In addition, accumulation of phosphate in root, stem and leaves was also analysed. It was observed that there was a differential efficiency in mycorrhizal colonization and the specificity of fungal symbionts to stimulate host to a significant growth response.
