Correlation coefficient (r) between the different physio-biochemical parameters under various concentration of PEG after 3 days of treatments.

For each parameter, average values of three AtDREB1A transgenic peanut lines along with WT were used. Where: PRO-proline, OP-osmotic potential, RWC-relative water content, EC-electrolytic leakage, CHL-chlorophyll content. The letters indicate the parameters followed by concentration of PEG followed by days of exposure to PEG (e.g. PRO10, Proline content at 10% PEG).* indicates a significant correlation: *P ≤0.05, and **P≤0.01.Correlation coefficient (r) between the different physio-biochemical parameters under various concentration of PEG after 3 days of treatments.
