Abstract
The effects of plant culture medium composition and strength on Glomus mosseae (BEG 12) spore germination were monitored. Aseptic spores were used to infect wild strawberry (Fragaria vesca), strawberry (Fragaria x ananassa) potato (Solanum tuberosum), onion (Allium cepa), tomato (Lycopersicon esculentum) and mungbean (Vigna radiata) in autotrophic culture in vitro. Three flavonoids, naringenin, hesperetin and apigenin were assessed for their effects on spore germination and root colonisation in autotrophic culture. All three compounds significantly promoted spore germination and, all but naringenin early hyphal growth. These effects were concentration and time dependent. All flavonoids were observed to increase the % root length colonisation by the AMF in A. cepa and L. esculentum; only apigenin promoted colonization in S. tuberosum.
