| Abstract | ||
| Puccinellia distans is a perennial range species from Poaceae family. The current research was performed to evaluate different priming treatments effect on improving seed germination in P.distans. For this purpose a factorial experiment with a completely randomized design in four replications with 3 priming treatments (9 levels) was conducted. Treatments included salicylic acid (100, 200 and 300 mg/l), gibberlic acid (125, 250 and 500 ppm) and ascorbic acid (100 and 300 mg/l). The time of each of mentioned treatments was considered 10, 24 and 8 hours, respectively. Distilled water was used as control treatment. Evaluated germination characteristics were percentage and rate of germination. Results indicated that priming application has had considerable influences on seed germination so that there are significant differences between obtained results. Priming with salicylic acid (at 300 mg/l level) had the highest effect on germination.It increased germination percentage up to 40% and germination rate up to 1.8 seed/day compared to control treatment. | ||
