Abstract
2 Abstract: Determining plant resistance to salinity, aridity and grazing is very important for selecting the favorable plant species for rangelands. The objective of this study was to compare the salinity, aridity and grazing tolerance of three rangeland species (Agropyron elongatum, Kochia prostrata and Puccinellia distans). The experiment was conducted in the greenhouse, with a factorial arrangement in a completely randomized design with 3 replications. Salinity levels of 4 (as control), 20, 30 and 40 dS/m; Aridity levels of field capacity irrigation (as control), -12 and -14 bars; Grazing levels of 0% (as control), 25%, 50% and 75% cutting were applied. The results showed that increasing salinity and aridity level decreased dry matter production and residual dry matter in all studied plant species. 25% cutting caused increased residual dry matter. Increasing grazing level increased dry matter production. The maximum survival scores were found in the lowest salinity, aridity and grazing level treatments. However, the minimum survival scores were observed in the highest salinity, aridity and grazing level treatments. Agropyron elongatum had the maximum and Kochia prostrata had the minimum salinity, aridity and grazing tolerance.

8 of 12 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.
Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
