The influence of different concentrations of herbicide systemic chevalier on physiological and biochemical parameters in spring wheat (Triticum aestivum L.)
Abstract
This research aims at finding the effect of different concentrations of systemic herbicide Chevalier on three varieties of Spring Wheat (cv Salama, ARZ and Hidhab). Grains of wheat, seedlings were germinated in plastic pots at 12 h photoperiod, 75% relative humidity and 26/14 °C day/night regime. When seedlings were 10 days old, irrigation water was substituted with Hoagland solution. At the 3 leaf stage, plants were divided into two groups for each variety; one was treated with Chevalier herbicide (control +four increasing concentrations (0.6, 0.9, 1.2 and 1.5 mg /pot). After 2 days leaves were collected, physiological and biochemical parameters were analyzed to characterize the specific response of each cultivar. Data show that pigment chlorophylls contents were strongly modified but were similarly affected by treatment herbicide. Alterations caused by the herbicide, were presented in the form of disturbances affecting the growth and biochemical metabolism of cereal. The results reveal the existence of oxidative stress generated by xenobiotic on the varieties studied, proportional to the concentration used. A large genotypic variability was observed response variety and put in evidence, mostly affects the antioxidant system.
