Effect of Saline Soils on the Functional State of Species of the Genus Artemisia

The effect of saline soils on the functional state of glycohalophytes of the genus Artemisia ( A . santonica , A. pauciflora , and A. lerchiana ) in the basin of Lake Elton (Prieltonye) is studied. It is established that the higher levels of water and Na + content in A . santonica leaves are correlated with a high content of pigments, carbohydrates, and phenolic compounds against the background of more intensive oxidative processes. It is noted that the accumulation of a significant amount of free amino acids is characteristic of the species A. pauciflora and A. lerchiana . At the level of structural components of membranes in A. pauciflora and A. lerchiana leaves, a high level of digalactosyldiacylglycerol and linolenic acid was recorded in the composition of the lipids of thylakoid membranes and an elevated concentration of phosphatidylcholine was found in nonplastid membranes.
