Effect of Glomus on common bean root colonization by arbuscular mycorrhizal fungi. Common bean genotype 115 grown in hydroaeroponic culture under P sufficiency (open bars) or P deficiency (grey bars) after inoculation with Glomus by mycorrhizal inoculant or by contact with mycorrhized Stylosanthes guianensis (hatched bars) both in sand pre-culture, and in sand culture (black bars). Data are means ± SD of means of three replicates plants harvested at 50 days after sowing.
