Abstract :

Germination and seedling establishment of the major stages in the life cycle of plants is influenced by various environmental factors. This study was designed to investigate the effect of seed priming on germination characteristics of forage maize plant was done. Priming treatments included four levels (zero, 1, 2 and 3 mM), salicylic acid and salinity of 4 concentrations (zero, 1, 2 and 3%) sodium chloride, respectively. Factorial experiments in completely randomized design with three replications at the Research Lab of the Faculty of Agriculture, Islamic Azad University, Shiraz was performed. Priming with salicylic acid improve percentage rate, the germination index. The results showed that the effect of priming with salicylic acid and salinity on the percentage, speed of germination index, see Index Seed, Seedling and rootlet weight was significant. Highest percentage, speed of germination index of seeds by salicylic acid, 1 and 2 mM prim and salinity was free environment. Vigor index of seeds by salicylic acid, 1 and 2 mM prim and salinity conditions were 1% had the maximum value. Salicylic acid concentration increased to 3 mM reduced traits was assessed in this study. Seedling fresh weight of the seeds by the concentration of 2 mM prim and salinity conditions were 2 percent was highest. Interaction among different concentrations of salicylic acid and sodium chloride showed no significant difference in terms of weight rootlet.
