Impacts of seed biopriming on antioxidant and total phenolic contents in rice seedlings. The percentage of DPPH radical inhibition referring to the antioxidant activity (a) and the total phenolic content (b) were measured in 14-day-old seedlings’ roots and shoots. Five bacterial isolates (CPS003, CZR007, CZS004, CZS006, and CZL003) were used for seed biopriming. Bioprimed unhealthy seeds (UHS) were tested in comparison with the controls made of non-treated (No) or hydroprimed healthy seeds (HS) and UHS. Error bars are mean values ± SDs of at least three replicated measurements. The statistical comparison of means between HS (μ1) and UHS (μ2) without priming was conducted using the independent-samples t-test at P = 0.05. The statistical differences of means compared by one-way ANOVA with Tukey’s post hoc test at P ≤ 0.05 are indicated with small case letters for every type of primed seeds (within the same priming duration) and with the Roman numbers for the comparison between any tests and controls. The data derived from any bioprimed seeds were calculated as a mean, regardless of the different bacteria tested
