Table 1 Relative water content (%) of two soybean genotypes (Coraline and Speeda) at 3 different sampling dates 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).
