The evaluation of the effect of salinity on seed germination and seedling growth in three species of Agropyron, Bromus and Secale

This research was conducted to determine the more salinity tolerant species of Agropyron desertorom, Bromus tomentellus, Secale montanum. Two genotype were selected for each species. The experiment was conducted based on a factorial design including five salinity levels of 0,100, 200, 300 and 400 mM Nacl and Cacl2 treatments.Data were recorded and analyzed for Chlorophyll(a) concentration (chl.a), Chlorophyll (b) concentration (chl.b) and total Chlorophyll(t) concentration (chl.t).The result of chlorophyllmetri revealed that there was a significant difference (P<0/01) between species, chl.a and chl.t had significant difference. In addition the study of intraction between species and salinity, Agropyron in highest different levels had the highest concentration of chlorophyll a.
