The effect on botanical and yield component in some agropyron species (Agropyron cristatum, A. desertorum and A. elongatum) of different salt concentrations

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 (Control, 5, 10 and 15 EC dS/m NaCl). In the research was investigated such morphological properties as plant height, root length, total plant height, root/shoot length ratio, fresh shoot weight, fresh root weight, total fresh plant weight, fresh root/shoot weight ratio, dry shoot weight, dry root weight, total dry plant weight, dry root/shoot weight ratio, dry matter ratio, seeds per Spica, the content of K, Na and Cl in stem and root of these plants. While increasing salinity dosages wasn't effect on A. desertorum's aboveground plant height in this study results, increasing salinity dosages were caused that A. elongatum's aboveground plant height was increased by 5.6%. Seeds per Spica obtained from three Agropyron species grown until grain filling duration were determined 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 %. Although the maximum content of K in the stem was found by 2.56 % in tall wheatgrass with 5 EC dS/m salt concentration, the minimum content of K was determined with control groups in desert wheatgrass (0.85 %). The content of K element in stem was increased with increasing salt dosages in Agropyron species, especially in tall wheatgrass. While the content of Na in stem by 0.51 % of tall wheatgrass grown in 10 EC dS/m salt concentration was the maximum content of Na in stem, the minimum content of Na was determined by 0.06 in control groups of crested wheatgrass. 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.
