We hypothesize that arbuscular mycorrhizal inoculation would give an advantage to overcome acidity and aluminium toxicity problems. To verify this hypothesis, zucchini plants inoculated
(+AM) or noninoculated (−AM) with AM fungi were grown in
sand culture with nutrient solution having different pH and alu-
minium concentration (pH 6.0, pH 3.5 or pH 3.5 + Al). +AM and
−AM plants were compared in terms of yield, biomass produc-
tion, fruit quality, SPAD index, electrolyte leakage, and mineral
composition.
