Figure 5. Sequential Equation Modeling for soil properties and
AMF-colonization rates of Ruellia nudiflora . Solid and dashed
lines indicate the positive and negative standardized paths,
respectively. Path coefficients for RS (green arrows), OUS (blue
arrows), and DUS (orange arrows) environments were reported together
when detected significantly different by a multigroup test (see
methods). Asterisks (*) denote path coefficients that are significantly
different from 0. Different letters indicate significant differences
between path coefficients. The SEM showed a good overall fit
(χ22 = 2.661, P =0.264; CFI = 0.99; RMSEA = 0.074; SRMR = 0.053), as well as a good fit
for RS (χ22 = 0.883, P =0.643; CFI = 1.0; RMSEA = 0; SRMR = 0.046), DUS
(χ22 = 1.211, P = 0.546;
CFI = 1.0; RMSEA = 0; SRMR = 0.046), and OUS
(χ22 = 3.287, P =0.193; CFI = 0.00; RMSEA = 0.179; SRMR = 0.092).
