Trifloxystrobin Pretreatment Alleviates Excessive Copper Stress in Wheat (Triticum aestivum L.)

Protective role of Trifloxystrobin pretreatment against excessive copper-related abiotic stress in Triticum aestivum L. was determined two Turkish wheat cultivars, Sönmez and Gerek 79. Ten-day-old seedlings were pretreated with 20 µM 80 Trifloxystrobin. A group harvested without exposure to as a control. Two days after, treated copper(II) chloride. Seedlings on the 20th day after sowing. The growth level groups evaluated by measuring length, fresh weight shoot dry shoots. Chlorophyll + b, carotenoid anthocyanin contents well proline levels assessed. Lipid peroxidation total activities superoxide dismutase, peroxidase glutathione reductase analyzed predict oxidative levels. Both cultivars exhibited similar responses treatments. doses did not cause damage plants when applied alone. subjected copper showed significant reductions parameters, chlorophyll pigments. Conversely, caused remarkable increase anthocyanin, malondialdehyde accumulation. Superoxide dismutase increased, while activity decreased copper-stressed plants. strengthens antioxidant defense system. All parameters positively affected pretreatment. As dose severity both genotypes. is promising method for reducing copper-induced T. aestivum.
