Fig. 6From: Evaluation of seed nitrate assimilation and stimulation of phenolic-linked antioxidant on pentose phosphate pathway and nitrate reduction in three feed-plant speciesa Superoxide dismutase activity (Unit.mg− 1 protein), b Catalase activity (Unit.mg− 1 protein) and c Guaiacol peroxidase activity (nmol.mg− 1 protein) of three feed-plant species (alfalfa, tall fescue and perennial ryegrass) after 2 weeks of germination with three seed nitrate treatments (5 mM KNO3, 10 mM KNO3 and 25 mM KNO3). Means with different letters are significantly different (p < 0.05) showing treatment differences among three speciesBack to article page
