Abstract
Bald cypress (Taxodium distichum) seedlings were grown at different levels of NaC1 (0, 17, 34, 68,102,136 and 170 mol m-3) in greenhouse during seven month growing season. Height, diameter growth and water consumption were measured during the experiment. Root, shoot and leaf weight were measured after harvesting in September. Na, P, Ca, K and Mg uptake in roots, shoots and leaves were measured. Seedling resistance to NaCl was considerable until 102 mol m-3, then at 136 mol m-3 the responses were quite different among seedlings and at 170 mol m-there was not any chance of survival at the end of the experiment. Growth at 34 mol m-3 was the highest. Water consumption of seedlings was almost similar at the levels of 0, 1 and 2 but declines to 53% in 102 and 15% in 170 mol m-3 NaCl in relation with controls. Height of seedlings was not a good indicator of plant response to salinity in this experiment for treatments 0-102 mol m-3 salinity, but diameter and root or shoot biomass were reliable indicators of salinity effects.
