Table 1.
Number of total and positive trap cultures and spore numbers of AMF per Land Use System.

1)
Traps = values represent the total number of traps established per LUS considering both localities (UFLA and FURB)
2)
Percentage of trap cultures that yielded newly formed AMF spores;
3)
Numbers represent the smallest – the highest number of spore recovered in a trap culture within each LUS;
4)
Mean number of AMF spores/50 ml soil. Means followed by the same letter within the column are not statistically different (Duncan’s test, P < 0.05).
