Effect of pH, temperature and nutrients on the germination of a vesicular-arbuscular mycorrhizal fungus, Glomus fasciculatum in vitro

The effect of various pH (5.5, 6.5, 7.5 and 8.5) and temperature (20, 25 and 30 deg. C) on germination of spores of Glomus fasciculatum on 1% water agar was studied. Maximum germination (81.3%) occurred at pH 6.5 at 25 deg. C. Spore germination was also studied with other nutrient media such as corn...

Description
Summary:The effect of various pH (5.5, 6.5, 7.5 and 8.5) and temperature (20, 25 and 30 deg. C) on germination of spores of Glomus fasciculatum on 1% water agar was studied. Maximum germination (81.3%) occurred at pH 6.5 at 25 deg. C. Spore germination was also studied with other nutrient media such as corn meal agar, modified Hepper medium, charcoal agar (0.01%) and soil extract agar. A significant increase was observed in charcoal agar and soil extract agar (+13.4% and +10.9% respectively)
