Lipid peroxidation and superoxide dismutase activity in pea seedlings under clinorotation.
Clinorotation-mediated changes have been determined in lipid peroxidation and superoxide dismutase (SOD) activity in Pisum sativum L. (cv.Uladovsky) seedlings. It was established, that clinorotation caused an increase in lipid peroxodation intensity in pea leaves and roots; the highest intensity was in the leaves. Simultaneously, the increased total, cytosolic and chloroplastic SOD activities were observed in clinorotated pea seedlings. These results indicated, that in response to the clinorotation-induced increase of lipid peroxidation, plant organisms mobilized enzymatic defence, that was an important property of their resistance under clinorotation.
