Özet
Salinity is a predominant problem in many arid regions of the world. Plant development in these regions is negatively affected by the high salt ion concentrations which have accumulated in the rhizo-sphere. This research aimed to determine the effects various salt concentrations (Control, 5, 10 and 15 EC dS m(-1) NaCl) have on three species of wheatgrass [crested wheatgrass (Agropyron cristatum), desert wheatgrass (A. desertorum), and tall wheatgrass (A. elongatum)] located in the Central Anatolian drought rangelands. The K%, Na% and Cl% content in the stems and the roots of these Agropyron species were determined at each stage of growth until seed production. The potassium uptake increased with salt application, most especially for the tall wheat grass species. The maximum Na% content recorded (i.e. 0.51%) was in the stem of tall wheatgrass at a salt concentration of 10 EC dS m(-1) NaCl; the minimum Na% recorded was for crested wheatgrass (i.e. 0.06 %) in the control group. It was determined that tall wheatgrass was more tolerant to salinity in regard to the other Agropyron species. Furthermore, with respect to literature, results indicated desert wheatgrass to be a much more salt tolerant species.
