چکیده

This study performed to evaluation of priming and priming duration effects on some germination’ characteristics of two canola cultivars (Zurika and Talayeh) as factorial randomized complete block design with three replications at the Besat Research Center, Fars Province, Iran. The first factor treatments included cultivars and second factor was salicylic acid in 3 levels (750, 1500 and 2250 M), ascorbic acid in 3 levels (200, 400 and 600 ppm), polyethylene glycol on 2 levels (-2 and -4 bar), potassium chloride 2 level (-5 and -10 bar) Brassinosteroid on 2 levels (20 and 40 micrograms per liter), gibberellic acid on 2 levels (100 and 200 mg), nano zinc chelate and nitrogen each at two levels (1 and 2 mg) and priming water, also third factor included priming duration at 3 levels (3, 6 and 12 h). Totally, according to result it was founded that priming had positive effect on germination characteristics also it was determined that gibberellic acid, salicylic acid and Ascorbic acid had highest effects incompared to other priming, with increasing of concentration and duration of priming, studied traits increased in responses to treatments. According to interaction between priming and duration, it was founding that highest radicle length (6.13 mm) and plumule weight (0.172 g) were obtained by BR20 for 3h duration, also KCL-5 treatment with 12h duration showed highest means for plumule length (4.19mm) and seedling length (52.37mm). The results showed that highest seedling weight (0.315 g), allometric coefficient (1.074) and weight vigor index (0.218) were obtained by GA100 for 3h,
