The present investigation was carried out during the year 2020 at four study sites. Corresponding to biochemical traits, peroxidase activity recorded was maximum in OP-13 (87.99 ΔOD min -1 g -1 FW) among plants, S3 (28.74 ΔOD min -1 g -1 FW) among sites. None of the OP X S interactions had significant effect on this trait. Highest catalase activity of 63.48 µmol H2O2 min. -1 g -1 FW was observed in OP-15 among plants, S3 (27.98 µmol H2O2 min -1 g -1 FW) among sites. This attribute had no significant influence among interaction treatments. OP-4 had maximum phenol content of 25.34 mg 100g -1 among plants, S3 (6.87 mg 100g -1 ) among sites and OP-4 X S3 (26.08 mg 100g -1 ) in interactins. Flavonoid content observed to be higher in OP-4 (1.86 mg 100 g -1 ) among plants, S3 (1.47 mg 100 g -1 ) among sites and OP-1 X S3 (2.50 mg100 g -1 ) among interaction combinations. Significantly higher proline content was recorded in OP-3 (158.76 μg g -1 ) among plants, S3 (37.94 μg g -1 ) among areas and OP-3 X S3 (183.00 μg g -1 ) among interactions. Malondialdehyde content recorded was highest in OP-15 (3.66 nmol MDA g -1 ) among species, S3 (2.02 nmol MDA g -1 ) among sites. OP X S combinations showed non significant influence on MDA content.
