Type: article
Abstract: The present study aimed to investigate the ameliorative effect of Indole Acetic Acid (IAA) on Zea mays plants grown under simultaneous stress of hexavalent chromium Cr (VI) and Macrophomina phaseolina. The plants were treated with 1% IAA and subjected to Cr (VI) (2000 and 4000 ppm) and M. phaseolina stress for 30 days. The results revealed that the application of IAA significantly improved the growth parameters and photosynthetic pigments, however, the antioxidant enzyme activities increased in stressed plants compared to the control. Furthermore, IAA treatment reduced the stress of Cr (VI) in the roots and shoots of the plants. These findings suggest that IAA protects Z. mays plants grown under the simultaneous stress of Cr (VI) and M. phaseolina by enhancing their physiological activities, thereby reducing the toxic effects of Cr (VI) and M. phaseolina.
