Statistical analysis of plant phenotypic data
The relative changes in shoot biomass, root biomass in the combinations
of the three plants and three rhizobacterial strains was analyzed with R
Studio (Version 3.5.2). First, the normality and homogeneity of variance
of the data was assessed and when the two assumptions were not met, the
data was subjected to Box-Cox transformation using the package MASS.
Differences were tested by two-way analysis of variance (ANOVA). A
Tukey-HSD test was used to separate group mean values when the ANOVA was
significant at p < 0.05. The ANOVA table is shown in
Supplementary Material, Table S1 . Differences between
rhizobacterial treatments and non-treated control on raw phenotype
parameters were compared by Student’s t -Test.
