Glomus mosseae (BEG 12) was studied in vitro and in
greenhouse trials. The presence of yeasts or their soluble
and volatile exudates stimulated the percentage spore
germination and hyphal growth of G. mosseae. Percentage
root length colonized by G. mosseae and plant dry
matter of soybean (Glycine max L. Merill) were increased
only when the soil yeasts were inoculated prior to the AM
fungus. Higher beneficial effects on AM colonization and
plant dry matter were found when the soil yeasts were
inoculated as an aqueous solution rather than as a thin
agar slice. Although soluble and volatile exudates of
yeasts benefited the AM symbiosis, their modes of action
were different.
