Biochemical status of plants under different stress conditions. Estimation of (a) free amino acids, (b) polyphenols, (c) starch, (d) total sugars, (e) reducing sugars, and (f) proline in peanut under individual and combined stresses (S-D: salinity and drought, S-H: salinity and heat, S-C: salinity and cold, D-H: drought and heat, D-C: drought and cold, S-D-H: salinity, drought, and heat, and S-D-C: salinity, drought, and cold). The data are the mean ± SE; different letters indicate significant differences at p < 0.05.
