Data analysis
For assessing plant growth parameters, enzyme activity, and gene
expression analysis, statistical significance was used for analysis of
variance (One-way ANOVA) in SPSS 22.0 (SPSS Inc., Chicago, IL, USA).
Duncan’s post-test (P <0.05) was used for multiple
comparisons. The results were expressed as the mean ± SE . In all
figures, different capital letters indicate significant differences
between same treatments, under the different water condition, whereas
the lowercase letters indicate significant differences between different
treatments seedlings under the same water condition. The experiment was
carried out with three biological replicates, and each experimental
index was measured by at least four replicates.
