In order to evaluate the effect of hormonal pretreatment on germination of cumin, an experiment was conducted at laboratory of Department of Agronomy and Plant Breeding, College of Agriculture, Shahid Bahonar University of Kerman in 2019 in a complete randomized design with 4 replication and 5 treatment. Treatments included control (without pretreatment), pretreatment with two concentrations of salicylic acid (0.25 and 0.5 mM) and pretreatment with two concentrations of brassinosteroid (0.5 and 0.75 μM). The results of analysis of variance showed that the effect of hormonal pretreatment were significant at 5% probability level on percentage of germination and germination rate of cumin. Means comparisons showed that the treatment which pretreated with 0.5 μM brassinosteroid with the highest percentage of germination and highest germination rate (48.1) showed significant difference compared to control treatment.
