Phytotoxicity of different mediums before and after Rh. mucilaginosa growth. a Polyphenol content of different AE before and after 4 days of Rh. mucilaginosa growth. b Percent of germinated seeds with different AE concentrations before and after 6 days of Rh. mucilaginosa growth. Bars show the mean and S.D. (n = 3); different letters indicate statistically significant differences (p ˂ 0.01)
