Characteristics of a Nitrate Reductase in a Barley Mutant Deficient in NADH Nitrate Reductase.

abstract：:Seedlings of maize (Zea mays L. cv Pioneer 3906), hydroponically grown in the dark, were exposed to NaCl either gradually (salt acclimation) or in one step (salt shock). In the salt-acclimation treatment, root extension was indistinguishable from that of unsalinized controls for at least 6 d at concentrations up to 10...
