^ISY seed yield per plant, RWC relative water content, Chla chlorophyll a, Chlb chlorophyll b, TChl total chlorophyll, Cars carotenoids, POX peroxidase, APX ascorbate peroxidase, CAT catalase, MDA malondialdehyde, TPC total phenolics content, TFD total flavonoids.
^¥ In each column (each trait) the means with similar letters are not significant at P < 0.01 by the LSD test. Values are means ± S.E. (replication = 3).
