Abstract:

Salinity effects on many plants developments in parallel with morphological properties and yield of plants. This study carried out greenhouse conditions in 2015-2016. It was aimed to determination of the effects on Agropyron species (Agropyron cristatum, A. desertorum and A. elongatum) of different salt concentrations (0, 5, 10 and 15 EC dS/m NaCl). In the research was investigated such morphological properties as aboveground plant height, total plant height (shoot and root height), fresh shoot weight, total fresh plant weight (shoot and root weight) and seeds per Spica. Increasing salinity dosages wasn’t effect on A. desertorum’s aboveground plant height in this study results. But increasing salinity dosages were caused that A. elongatum’s aboveground plant height was increased by 5.6% while aboveground plant height of A. cristatum was decreased by 4.6%. Seeds per Spica obtained from three Agropyron species grown until grain filling duration were observed that accordingly control groups’, seeds per Spica of A. cristatum, A. desertorum and A. elongatum were decreased by increasing salt concentrations respectively 62.5 % 61.7% and 42.8 %. Our findings show that A. elongatum was less impressed by salinity conditions more than other Agropyron species.  This results show that A. elongatum was more adaptable in salinity conditions in terms of morphological.
