A greenhouse experiment was carried out, to determine yield, growth, fruit quality, SPAD index, electrolyte leakage, and mineral composition of zucchini squash (Cucurbita pepo L.) inoculated (+AM) and noninoculated (−AM) with arbuscular mycorrhizal
and cultured in pots filled with quartziferous sand. Plants were supplied with nutrient solutions having
different pH and aluminium concentration (pH 6.0, pH 3.5 or pH 3.5 + Al).
