Abstract:

Herbicides have been used in the crop field to increase the crop productivity and grain yield. But unfortunately since long back all research papers and articles showed the effect of this herbicide on the non-target organisms. The purpose of this study was to test the toxicity of two herbicides (Sekator and Zoom) on the biochemistry of hard wheat: Triticum durumDesf and common wheat: Triticumaestivum L. The herbicides were applied at tillering stage in the dose full recommendeddoses. After eight days of treatment leaves were collected to determine differentparametersof proteincontent and enzyme activity involved in the antioxidant system (ascorbate peroxidase: APX).The results validated by statistical analysis revealed that there was a highly significant decrease in proteincontent in plant samples treated with the herbicide Zoom in Hidhab variety. By contrast, exposure to the herbicide Sekator causes significant variation in APX activity. Peroxidase activity were significantly decreased in Waha variety but it was significantly increased in Hidhab (HD), and APX activity increased compared with controls in HD treated with Zoom herbicide.The decrease in protein content is an indication of reduction in the growth of the plants leading to a decrease in the yield, while increased level of peroxidase activity pointed to the occurrence of a scavenging mechanism.
