This study was carried out to investigate whether plant growth regulators (PGRs) could affect lipid peroxidation (Malondialdehyde = MDA level) in erythrocyte, muscle, liver, heart and kidney tissue. Eighteen Sprague-Dawley albino rats were divided into three experimental groups: control and PGR-treated (indoleacetic acid and kinetin). Seventy-five ppm of PGRs, indoleacetic acid (IAA), and kinetin were administered orally to 6 rats ad libitum for 25 days. The hormone treatments caused different effects on the level of malondialdehyde (MDA) to those of the control rats. According to the results, while liver and kidney MDA levels were increased significantly by IAA administration in rats, kinetin did not affect the MDA levels in erythrocyte and other tissues. It was concluded that IAA might affect lipid peroxidation in animals at subacute treatment.
