In a pot experiment, burning or clipping of Trifolium pratense plants colonized by the vesiculararbuscular mycorrhizal (VAM) fungus Acaulospora scrobiculata increased the number of spores in the substrate and the abundance of vesicles. The length of external mycelium and inoculum potential increased with clipping, but decreased with plant burning. Results suggest that the loss of photosynthesising tissue does not explain the effect of burning on VAM propagule activity.
