Extracts of medicinal plants can be used as biostimulants to overcome environmental stress conditions in cultivated plants. Herbicides are commonly used for weed control in wheat fields and accepted as abiotic stress factors for both weeds and cultivated plants. This study was aimed at determining the effects of rosehip (Rosa canina L.) fruit extract (20 %, 10 ml/pot, R) and tribenuron methyl (1 g/acre, H) on the antioxidant system in two wheat varieties (drought-tolerant Triticum aestivum cv. ‘Tosunbey’ and drought-sensitive cv. ‘Sultan-95’). Wheat seedlings were divided into four groups: non-treated seedlings (C, Control), seedlings treated with rosehip fruit extract (R), seedlings treated with tribenuron methyl (H), and R seedlings treated with tribenuron methyl at the 28th day of the experiment (20 %, 10 ml/pot) (HR). R treatment increased root-shoot elongation in the ‘Tosunbey’ variety. All treatments decreased chlorophyll content in ‘Tosunbey’ but did not change it in ‘Sultan-95’. R treatment did not alter superoxide dismutase (SOD) isoenzyme amount and peroxidase (POX) activities in ‘Sultan-95’ but increased lipid peroxidation (LP). However, ‘Tosunbey’ showed a low SOD isoenzyme amount and stable LP and cell membrane permeability (CMP). Thus, R treatment provided difference between these varieties. R treatment caused stable LP in the drought-resistant variety and increased it in drought-sensitive variety. LP did not decrease due to decrease in SOD isoenzyme amount and POX activity in ‘Sultan-95’ after HR treatment. However, HR treatment decreased LP and CMP and showed increased POX activity in ‘Tosunbey’. Consequently, it was assumed that rosehip fruit extract treatment protects by inducing POX activity in the drought-resistant variety after herbicide treatment.
