The effect of different salinity level and synthetic compounds treatment on phospholipase D activity in the root tissue of maize seedlings and the content of phosphatidic acid in plasmatic membrane has been investigated. The salt exposition to 0.05 M NaCl raised the activity of phospholipase?D and the content of phosphatidic acid in the plasma membrane. The salt exposition to 0.1?M NaCl lowe­red the activity of phospholipase D, but raised the content of phosphatidic acid in the plasma membrane. The synthetic compounds treatment increased the activity of phospholipase D. It was shown that methyure treatment decreased the content of phosphatidic acid in the plasma membrane. The ivin treatment had the opposite effect.

Key words: Zea mays L, phospholipase?D, phosphatidic acid, plasma membrane, salinity stress.
