Values represent means of three biological replicates ± SD. Different letters within the columns represent significant difference among the treatments at p ≤ 0.05, derived from Tukey HSD.
*** represent significance at p ≤ 0.05, p ≤ 0.01, and p ≤ 0.001, respectively, derived from two-way ANOVA.
ns, not significant. As, arsenic; AMF, arbuscular mycorrhizal fungus; NRS, non-reducing sugars; RSS, reducing sugar; TSS, total soluble sugars; HSD, honestly significant difference.
