The total nitrogen of the maize embyronic axis (root + shoot) from seedlings raised with 10 mM Ca(NO(,3))(,2) for 5 days was substantially higher than that from the control when 0.01 mM salicylic acid was supplied. As supply of high (1 mM) concentrations of salicylic acid decreased the accumulation of organic nitrogen. The in vivo activity of nitrate reductase in the roots increased at low concentrations of salicylic acid, while high concentrations were inhibitory. The stimulative
