Figure 4. Glomalin production after grazing simulation.

Glomalin production per mg hyphal dry weight in G. intraradices in in vitro culture, as a response to rising intensity in mechanical injury of the hyphae, induced by clipping. The injuries had to be undertaken on an existing mycelium and was therefore not present since experimental start as in the salinity and osmolarity treatments. Intensities should therefore not be directly compared.
