In laboratory bioassays, the aqueous extracts of canola grown in higher concentrations of ascorbic acid, (3,5,7 mm) decreased the germination, radicle growth and activities of catalase, peroxidase, ascorbate peroxidase and poly phenol oxidase enzymes in cultivars of soybean. The inhibitory effects of canola root extract was more on the growth and antioxidant enzymes activity in cultivar ‘DPX’ than shoot extract. While shoot extract of canola, caused more reduction in growth and antioxidant enzyme activity in cultivar ‘Sepideh’. The ascorbic acid increased the allelopathic effects of canola on soybean.
