Abstract :
    ermination is one of the most critical stages of a plant s life cycle. Also, drought stress is one of the severe environmental limitations for plants, which causes disturbances in seedling growth and plant establishment. The purpose of this research is to investigate the effect of seed priming with humic acid and seaweed extract on hyssop germination indicators. This research was factorial in the form of a completely randomized design, in ten treatment levels (hydropriming, algae 0.5%, algae 1%, humic acid 150 mg/liter, humic acid 300 mg/liter, combination of algae 0.5% + humic acid 150, combination Algae 0.5% + humic acid 300, algae combination 1% + humic acid 150, algae combination 1% + humic acid 300 and control) were carried out in three replications and morphological and germination traits were investigated. The results show that seed priming in the treatments of hydropriming, humic acid 150 and 300 mg/liter and compounds containing less percentage of seaweed caused an increase in six investigated indicators. It has germination indicators
