This study was carried out in 1398 in Seed Physiology and Technology Laboratory of Agriculture Faculty of Mohaghegh Ardabili University to investigate the effect of seed coating and priming on canola seed germination. Experimental treatments included humic acid, seaweed extract, amino acid each at 3 levels, growth stimulus combination (humic acid, seaweed extract, amino acid) at 4 levels, hydropriming with second level humic acid, hydropriming to The second level of seaweed extract and control treatment included 16 treatments. Results showed that seed coating and priming had positive effects on emergence percentage and emergence rate. Seed coating treatments with level 2 of seaweed extract, level 1 humic acid as well as control treatment had the highest percentage of emergence compared to the other treatments, while the percentage of emergence in the second level of humic acid priming was lower than other treatments. Was. Among different seed treatments, priming + second level of seaweed extract and priming with second level of humic acid had the highest rate of emergence rate of 0.01150 and 0.01129 / h, respectively, and 3 amino acid and 3 alga extract levels, respectively. Seabirds had the slowest emergence
