Effect of seed priming with PEG and soil moisture stress on sorghum APX, CAT, POD, SOD, MDA, and O²⁻ activities.

<p>(a) Ascorbate peroxidase (APX), (b) catalase (CAT), (c) malondialdehyde (MDA), (d) hydrogen peroxide (H₂O₂), (e) peroxidase (POD), and (f) superoxide dismutase (SOD) activities in sorghum seedlings. Unprimed or primed sorghum seeds were germinated under (I) unstressed soil moisture environment (Unstressed control), (II) drought, (III) excessive soil moisture stress (EM), (IV) 8 d drought stress followed by EM, and (V) 8 d EM followed by drought stress. Measurements were conducted at 12 and 24 days after planting (DAP). Data presented are means ± standard errors.
