Effects of Exogenous Application of Indole-3-Butyric Acid on Maize Plants Cultivated in the Presence or Absence of Cadmium

Auxins are plant hormones that affect plant growth, development, and improve a plant’s tolerance to stress. In this study, we found that the application of indole-3-butyric acid (IBA) had diverse effects on the growth of maize (<i>Zea mays</i> L.) roots treated without/with Cd. IBA cause...

In this study, we found that the application of indole-3-butyric acid (IBA) had diverse effects on the growth of maize (<i>Zea mays</i> L.) roots treated without/with Cd. IBA caused changes in the growth and morphology of the roots under non-stress conditions; hence, we were able to select two concentrations of IBA (10<sup>−11</sup> M as stimulatory and 10<sup>−7</sup> M as inhibitory). IBA in stimulatory concentration did not affect the concentration of H<sub>2</sub>O<sub>2</sub> or the activity of antioxidant enzymes while IBA in inhibitory concentration increased only the concentration of H<sub>2</sub>O<sub>2</sub> (40.6%). The application of IBA also affected the concentrations of mineral nutrients. IBA in stimulatory concentration increased the concentration of N, K, Ca, S, and Zn (5.8–14.8%) and in inhibitory concentration decreased concentration of P, K, Ca, S, Fe, Mn, Zn, and Cu (5.5–36.6%). Moreover, IBA in the concentration 10<sup>−9</sup> M had the most positive effects on the plants cultivated with Cd.
