Abstract
Effect of Cr3+ concentrations (1, 2, 4, 6, and 8 mg L-1) on lipid peroxidation / MDA production and antioxidative enzyme activity (APOX, SOD, and PPOX) in root and leaf tissues of sweet basil seedlings (Ocimum basilicum L.) during 6week treatment in hydroponic culture was studied. Increasing Cr3+ in the culture medium (≥4 mg L-1) caused significant enhancement of APOX, SOD, and PPOX activity in root and leaf tissues of sweet basil seedlings, compared with the control (P≤0.01). Introducing of ≥4 mg L-1 Cr3+ to the culture medium of sweet basil seedlings caused enhancement of MDA level in root and leaf tissues compared with the control (P≤0.01) indicating Cr-induced oxidative stress and membrane lipid peroxidation in basil seedlings under treatment.
