Abstract :
Seed priming is a technique that by means of seeds before sowing and confronting to condition of ecological environment in terms of physiologicaly and biochemically gain fitness for germination. In fact it is a type of presowing treatment. The aim of this study was comparison the effect of several methods of priming on germination and seedling growth of canola under salinity stress in comparative to Nanocide. For this purpose an experiment was conducted in a factorial design with four levels of salinity include 10, 12, 18, 24 dS/m Nacl and one control with three replications. The germination behavior of canola RGS cultivar treated with Nanocide in concentration of 0,20,40 ppm and ascorbate priming in three levels 100,200,400 ppm and hydropriming with distilled water was evaluated. Treatment with nanocide resulted in growth improvement and successful seed establishment, although percentage and rate of seed germination reduced. Priming treatments had a positive effect on germination rate and percentage but had no effect on seedling growth. Seeds treatment that caused increase of seedling growth had more importance under salt stress. With attention to results the best treatment in saline and non saline environment was nanocide treatment in 200ppm level. In fact nanocide in this concentration improved establishment of canola seeds in saline land.
