Table 2 Effect of salinity on AMF spore density (spore number g−1 dry soil; SD) and intensity of root colonization (I) of three eucalyptus clones (H4, H8, P6) pre-inoculated with various species of AMF after 90 days of cultivation at three salinity levels. AMF1; Glomus sp.2, AMF2; G. albida, AMF3; G. decipiens, and control (C); without pre-inoculation.
