摘要
The influence of endo- (Glomus mosseae) or ectomycorrhizal fungi (Laccaria laccata) and of bacteria (Enterobacter agglomerans, Agrobacterium sp., Agrobacterium radiobacter) on root exudation of maize, pine and beech seedlings, respectively, were studied in a growth chamber or in a greenhouse. Rhizospheric microorganisms modify the total release of carbon in the rhizosphere, the amounts of soluble exudates and their composition in carbohydrates, aminoacids and aliphatic acids. Such modifications influence the carbon balance, the humification processes and the bioweathering of minerals in the rhizosphere.
