Effects of inoculation with a commercial formulation of AM fungi on percent colonization by AM fungi in rice plants grown in field (A) and greenhouse (B) conditions in two types of soil (Crowley and Mamou). Soils were either treated with mycorrhizal (grey bars) or with nonmycorrhizal inoculum (white bars). Quantification of colonization was carried out from four field experiments and one greenhouse experiment in 2014–2015. Experiments were designated as: Rice Water Weevil Mamou 1 (RWW-M1), Rice Water Weevil Mamou 2 (RWW-M2), Rice Water Weevil Crowley 1 (RWW-C1), Rice Water Weevil Crowley 2 (RWW-C2), and Fall Armyworm 1 (FAW-1). Root colonization was evaluated twice in RWW-M1 (pre- and post-flood) and once (pre-flood) in the other experiments. Percentages are means ± SE, n = 5. Different letters accompanying bars indicate means that differ significantly (LSD, P ≤ 0.05). See Table 1 for details of ANOVA results.
