The absorption of NO(3) (-) by barley (Hordeum vulgare L.) was investigated by following the disappearance of NO(3) (-). The absorption was related to several parameters: NO(3) (-) and Ca(2+) concentrations, pH, and the presence of various anions. Absorption rate increased with increasing Ca(2+) concentration, reaching a maximum at approximately 5 mm Ca(2+), and was considerably inhibited by NH(4) (+). Absorption was influenced markedly by pH, and little or not at all by anions (Cl(-), Br(-), SO(4) (2-)), and was decreased by respiratory and oxidative phosphorylation inhibitors.
