Table 1.
Significance level of effects of different factors and factor interactions on variables based on two-way analyses of variance (ANOVA).
Fig 1.
Colonization rates of S. photeinocarpum.
Values are presented as means ± SD for the five replicates. Different letters indicate a significant difference (p < 0.05) according to the LSD test.
Fig 2.
Dry biomasses and P concentrations of S. photeinocarpum.
M = mycorrhizal inoculum; NM = non-mycorrhizal inoculum. Values are presented as means ± SD for the five replicates. Different letters indicate a significant difference (p < 0.05) according to the LSD test.
Fig 3.
Cd concentrations and Cd uptakes in S. photeinocarpum.
M = mycorrhizal inoculum; NM = non-mycorrhizal inoculum. Values are presented as means ± SD for the five replicates. Different letters indicate a significant difference (p < 0.05) according to the LSD test.
Fig 4.
Soil DTPA-extractable Cd concentrations.
M = mycorrhizal inoculum; NM = non-mycorrhizal inoculum. Values are presented as means ± SD for the five replicates. Different letters indicate a significant difference (p < 0.05) according to the LSD test.
Fig 5.
CAT, APX, POD and SOD activities in the leaves of S. photeinocarpum.
CAT, APX, POD and SOD represent catalase, ascorbate peroxidase, guaiacol peroxidase and superoxide dismutase, respectively. M = mycorrhizal inoculum; NM = non-mycorrhizal inoculum. Values are presented as means ± SD for the five replicates. Different letters indicate a significant difference (p < 0.05) according to the LSD test.
Fig 6.
GR activity, and contents of GSH, ASA and MDA in the leaves of S. photeinocarpum.
GR, GSH, ASA and MDA represent glutathione reductase, reduced glutathione, ascorbate and malonaldehyde, respectively. M = mycorrhizal inoculum; NM = non-mycorrhizal inoculum. Values are presented as means ± SD for the five replicates. Different letters indicate a significant difference (p < 0.05) according to the LSD test.
Fig 7.
Phytochelatins (PCs) production in the leaves of S. photeinocarpum.
M = mycorrhizal inoculum; NM = non-mycorrhizal inoculum. Values are presented as means ± SD for the five replicates. Different letters indicate a significant difference (p < 0.05) according to the LSD test.
