The influence of growth conditions (soil, climatic, biotic factors) on physiological and biochemical characteristics of plants of Salicornia perennans, native to Middle Volga and the Lower Volga basin. Plants were succulent appearance. It was found that the increase in water content of plant leaves (17 %), due to the gradual strengthening of climate aridity and strong enough impact on the processes of synthesis and disintegration of biopolymers, such as proteins and lipids. It demonstrated the potential use of species of the genus Salicornia (on example of S. perennans) as oilseed and/or energy saturated culture
