Table IV
Nutrient concentration in needles of P. halepensis seedlings inoculated with three ectomycorrhizal fungi under different N fertilisation sources (ammonium nitrate-NH4NO3,ammonium-(NH4)2SO4, nitrate-HNO3). For each inoculation treatment, different letters indicate significant differences (Duncan’s test, p ≤ 0.05).
