Effect of Glomus, Gigaspora and Acaulospora on: shoot phosphorus content (%) and phosphorus use efficiency of common bean. Common bean genotype 115 (A and A') inoculated with Glomus, Gigaspora and Acaulospora, and recombinant inbred genotypes 115, 147, 83, 7, 28 and Flamingo (B and B') inoculated with Glomus, grown in hydroaeroponic culture under P sufficiency (open bars) versus P deficiency (grey bars) or in sand culture (black bars). Data are means ± SD of three replicates harvested at 50 days after sowing. For each cultivation system, different letters indicate significant differences between treatment means.
