Effect of Chloride and Sulphate Types of Salinity on the Nicotinamide-adenine-dinucleotides in Pea Root Tips

It was shown that in pea root tips grown in media salinatedwith NaCl the content of NAD + NADH decreased while the contentof NADPH+NADP increased with increasing salinity. In pea roottips, grown in sulphate salinated media, only the decrease inthe content of NAD+NADH was noted. The content of NADPH+NADPin such root tips remained more or less constant. The implicationof these results and of previous results for the explanationof the nature of salinity damage was discussed.
