The effects of the soil yeasts Rhodotorula
mucilaginosa, Cryptococcus laurentii and Saccharomyces kunashirensis on the arbuscular mycorrhizal (AM) fungus
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. |
