Within a column, means at the same DAT followed by the same letters are not significantly different by the LSD test at P≤0.05 under completely randomized design. Data were analyzed separately at each measurement time. Values are expressed as mean±SE (n=3). DAT: days after treatment; ALS: acetolactate synthase; GST: glutathione transferase; OD₅₃₀: optical density at 530 nm; FW: fresh weight
