Abstract
Determining plant resistance to salinity is very important for selecting the favorable plant species for saline rangelands. The objective of this study was to compare the salinity tolerance of three rangeland species (Agropyron elongatum, Kochia prostrata and Puccinellia distans). The experiment was conducted in a greenhouse, with a factorial arrangement in a completely randomized design using 5 replications. Salinity levels of 4 (as control), 20, 30 and 40 dS/m were applied. The results showed that increasing salinity level caused reduction in shoot height, shoot dry weight, root length, root weight and survival scores in all studied plant species. The maximum length and weight of the roots and the maximum height and weight of the shoot and the survival scores were found in the lowest salinity level (4 dS/m) treatment. However, the minimum length and weight of the roots and the minimum height and weight of the shoots and the survival scores were observed in the highest salinity level (40 dS/m) treatment. Among the studied species, Agropyron elongatum had the maximum and Kochia prostrata had the minimum salt tolerance.
