Abstract

In order to study the effect of DROUGHT and SALINITY STRESS on three range species of Agropyron intermedium, Avena barbata and Panicum antidotale a study was carried out using factorial statistical method with a completely randomized design in 3 repetitions of 36 treatments totaling 108 vessels in greenhouse. DROUGHT STRESS was selected based on irrigation intervals of 6, 12 and 20 days. SALINITY STRESS was selected in the form of four SALINITY treatments, including zero (authentic), 40, 120 and 200 millimolar. Salt solutions of NaCl (60%), Na2S04 (30%) and CaCl2 (15%) were used. Two months duration of STRESS was applied. During the test, some observations including: the weight of STEM, leaf and ROOT DRY MATTER, RELEVANT HUMIDITY and potential water in leaves, the ratio of ROOT to leaf, the percent of leaves shedding, as well as the effects of STRESS on internal parts of organs, longitudinal and latitudinal sections of the plant, were carried out. The results show that dry and SALINITY STRESS will severely decrease DRY MATTER (stem, leaf and ROOT). The effect of 20 days dry treatment and 200 millimolar SALINITY was observed in decreasing DRY MATTER production more than the other treatments. Among the under test species, Avena barbata and Agropyron intermedium have the most and least tolerance to DROUGHT STRESS respectively, while the three studied species are not easily influenced by SALINITY STRESS.
