Abstract

Salad burnet has a lot of importance from different points of views, such as medicinal and forage purpose. This research was carried out to estimate the salinity resistance of salad burnet at seed germination stage. Five NaCl Levels 0, 50, 100, 150 and 200 mM treatments were used in five replication in a Complete Randomized Design experiment. Seed germination percentage was increased by increasing of NaCl concentration upto 150 mM, However decreased at 200 mM NaCl. It means appropriate salt concentration, is necessary for seed germination. By incresing salt concentration the radicle length and plumule length decreased. Analysis of variance of data showed that effects of different salinity treatments on percent of germination, radicle lengh and plumule length characters were statistically significant and characters of radicle length and plumule length had a linear trend, whereas, percent of germination had squared trend. The corrolation coeficient between any two characters of radicle and plumule length and percent of germination was positive and significant
