| Summary: | Seed priming improves some properties of seedling. The objective of this research was to evaluate the effect of salicylic acid and gibberellins on germination characteristics and changes of biochemically of sunflower seeds under accelerated aging, experimental design was factorial with complete randomized design as base design with 3 replications. The first factor was priming by salicylic acid and gibberellin, secondary factor was combinations 4 levels of aging (0, 2, 4 and 6 days of aging at 41°C). The results showed that the priming and aging effects on germination percentage, germination index, normal seedling percentage, seedling length, vigor index, abnormal seedling percentage, catalase and ascorbate peroxidase were significant, but on mean time to germination not significant. Results showed that, the highest germination characteristics were attained from priming by salicylic acid and gibberellins under non aged conditions. Also, seed priming increases enzyme activity. |
