Abstract
It was found out that the growth and development of Nitraria individual plants and the area of existence of its populations in landscape are determined by the type and level of salinization. It was determined that the range of favourable ecological contents of salts in soils for Nitraria under sulfate conditions is wider (0,7-3,4 %) than under chloride conditions (0,2-0,6 %). Plants are showing some adaptive behavioral reactions, which contribute to maintenance of optimal salts level within the bounds of their locations in response to changes of the level of salinization.
