The Elemental Compositionin Aboveground and Underground Organs of Some Agropyron Species Grown in Different Salt Concentrations
Salinity, which is more common in semi-arid and arid areas, is increasingevery day with climate change, poor quality irrigation water, and soil structure.High salt concentration restricts plant production and causes productivity lossin agriculture. To sustain agriculture in saline soils, the determination of plantspecies resistant to salinity comes into prominence in areas with salinity problems. For this reason, the research was performed to determine the nutrients(Ca, Mg, P, S, B, Cu, Fe, Mn, and Zn) accumulating at aboveground and underground parts of the three different Agropyron species, namely Agropyroncristatum, A.desertorum and A. elongatum (Syn. Elymus elongatus) underdifferent salt concentrations (control, 5, 10 and 15 EC dS m-1NaCl). A.cristatum, A.desertorum, and A. elongatumspecies, which are quality foragecrops grown in drought and salinity conditions, were determined to Ca content1.03%, 1.01%, and 1.49% respectively, and Mg content. 0.13%, 0.11% and0.20% respectively. As salt concentrations increased, Ca, Mg, Cu, Fe, Mn, andZn in the aboveground organ has increased compared to the control treatmentbut decreased in the underground organs. Ca and Mg content of the aboveground organs of A. elongatum grown at 10 EC dS m-1NaCl increased by 204%and 98%, respectively, compared to the control. Fe content of thewheatgrassspecies in saline conditions was found quite high, and an average of788 mg kg-1of Fe was found in underground organswhile this value was as430mg kg-1in aboveground organs. The results showed that A. elongatum hadmore nutrient elements in both underground and aboveground parts of the cropby comparison to the other two Agropyron speciesunder increased salinitylevels.
