The effect of different salt concentrations on germination characteristics of Mint

salinity is very important to evaluate changes in plant a major problem of arid and semi-arid regions is environmental stresses like salinity. To study the effect of salinity on germination characteristics of Mint, a completely randomized experiment was conducted under controlled conditions (germinator) with three replications in 2012. The experimental treatments included different salinity levels (0, 2, 4, 6 and 8 ds m-1). The studied traits included seedling length and dry weight, germination percentage and rate and seed viability index. It was found that salinity significantly decreased germination rate and percentage and seed viability index of Mint, but its effect on seedling length and weight was not different in levele of 0, 2, 4 and 6 ds m-1. In total, it can be concluded that salinity stress mainly decreased germination percentage and rate and seed viability index of Mint.
