Abstract

The main objective in this study was to determine seed GERMINATION rate and seedling growth of Agropyron desertorum and A. cristatum using factorial complete randomized block design with six SALINITY treatments of 0, 100, 200, 300, 400 and 500 mM NaCl . Seeds were incubated at 4°C for a few days and then surface-sterilized with 5% (v/v) sodium hypochlorite. The experiment was carried out in a germinator with 50% relative humidity at 25°C with a photoperiod of 8:16 hrs light/dark. Percent GERMINATION, PLUMULE and RADICLE lengths and seed GERMINATION rate were measured and the data were analyzed using ANOVA and Duncan"s multiple comparison test. The results showed no significant differences between A. desertorum and A. cristatum with respect to seed GERMINATION rate and RADICLE and PLUMULE lengths. The interaction effect between species and SALINITY and the replication effect on GERMINATION and lengths of RADICLE and PLUMULE were neither significant. The effect of various SALINITY levels on seed GERMINATION and RADICLE and PLUMULE lengths was significant at 1%. Growth of RADICLE and PLUMULE and seed GERMINATION were stopped at 200 and 300 mM NaCl, respectively. SALINITY levels at 0, 100, 200 and 300 mM had significantly different effects on seed GERMINATION. SALINITY levels of 0, 200 and 300 mM had significantly different effects on PLUMULE and RADICLE growths. Overall, seed GERMINATION rate, percent GERMINATION, lengths of PLUMULE and RADICLE declined with increasing SALINITY concentration.
