Figure 8

Actual photochemical efficiency of PSII of two soybean genotypes (Coraline and Speeda) at 3 different sampling dates (A: 3 days after drought stress application at R1 stage, B: 3 days after R3 stage started, C: at the end of R4 stage) as affected by hydrogen peroxide foliar spray application under drought stress conditions (D: drought from R1 till R2 stage, D1: drought from R1 till R2 stage + 1 mM hydrogen peroxide, D5: drought from R1 till R2 stage + 5 mM hydrogen peroxide, D10: drought from R1 till R2 stage + 10 mM hydrogen peroxide, CD: continuous drought starting from R1 stage, CD1: continuous drought starting from R1 stage + 1 mM hydrogen peroxide, CD5: continuous drought starting from R1 stage + 5 mM hydrogen peroxide, CD10: continuous drought starting from R1 stage + 10 mM hydrogen peroxide). All values are the means of 3 replicates (columns) ± standard errors (vertical whiskers). In each genotype, different letters indicate significant differences at .05 level as indicated by Duncan’s multiple range test.
