Abstract
Abstract This study was carried out on the germination properties and seedling parameters effects of some NaCl doses (control (0) -50-100-150-200 mM) applied to three barley Hordeum vulgare L. cultivars (Kral-97, Altikat and Larende). The study was carried out in the Laboratory of field crops Department of the Faculty of Agriculture of Van Yuzunc Yil University in 2019 according to the experiment two way completely radomized design in petri dishes with 4 replications. According to results of germination parameters; the effects of cultivars on average germination time were significant (p<0.05). The effects of salt doses on all germination parameters were significant (p <0.05). The effects of varieties and NaCl interactions on the differences in all parameters were insignificant (p˃0.05). According to the average, the lowest germination power and germination rates were taken from 150 mM NaCl applications and therefore it was observed that these two properties decreased by 15.56% compared to control (0). The effects of salt doses and NaCl interactions on all parameters were significant (p<0.05) while the effects of varieties other than hypocotyl length were insignificant (p ˃0.05) and the effects on all remaining parameters were significant (P < 0.05). Increased salt doses have been observed to have a negative effect on all parameters. It was determined that the Larende cultivar had a more salt-resistant performance in terms of all its properties, followed by the Kral-97 variety in general.
