Abstract: (31 Views)
To investigate the effects of the herbicide Super Gallant on morphological and biochemical activities and hormonal responses of sunflower (Helianthus annuus L., cv. Lakomka) under magnetized water treatment, an experiment was conducted in a completely randomized design with four herbicide concentration levels (0, 25, 50, and 75 mg/L) and three replications. The study was carried out in the growth chamber of the Biology Department, Urmia University, in 2018. Pots were irrigated with distilled water (control plants) and magnetic water (treated plants) for the first two weeks of the growing period, and with half-strength Hoagland's solution every other day from the third week. At the 4-6 leaf stage, different concentrations of herbicide were sprayed onto the aerial parts of the plants. The effects of the herbicide on the measured parameters were evident in both control and magnetic water-treated plants. A significant increase in gibberellin content was observed in magnetic water-treated plants, while a decrease in shoot auxin content was observed in both groups of plants. Root auxin content increased in control plants, and proline and soluble sugar contents increased in both groups of plants. Protein content and dry weight decreased significantly in both groups of plants. Under super gallant herbicide stress, as the herbicide concentration increased, the amount of damage to the plant increased, and the plant responded by increasing proline and soluble sugar levels.
