The aim of this study is to determine the effects of salicylic acid (SA) priming on the germination and seedling development of psyllium (Plantago ovata L.) seeds. The research was conducted at the Field Crops Laboratory of the Faculty of Agriculture, Siirt University, under controlled conditions at 25±1 °C. The plant material of the study consisted of P. ovata genotype originating from India. The laboratory study was set up in Petri dishes with 4 replications according to randomized complete plots design. In the study, four different doses of salicylic acid, namely 0.25 mM (SA1), 0.50 mM (SA2), 1.0 mM (SA3), and 2.0 mM (SA4), as well as a control (C) without salicylic acid and priming with distilled water (hydropriming), constituted the subject of the research. In the study, seeds germinated every 24 hours from the day of establishment were counted, and the experiment was concluded on the 7th day. At the end of the research, seedling fresh weight was determined based on 10 randomly selected plants from each Petri dish. Germination parameters such as germination percentage, average germination time, germination uniformity coefficient, germination index, and germination energy, as well as seedling parameters such as seedling fresh weight and seedling vigor index, were investigated in the study. According to the research results, SA treatments had significant effects on the germination parameters examined. It was concluded that SA application, as a simple and cost-effective seed pre-treatment method, had positive effects on the germination of psyllium, increased the germination percentage compared to the control, and accelerated germination by reducing the mean germination time. It can be said that the 0.25 mM dose of salicylic acid is the most effective dose for all germination and seedling growth parameters. As a result of the research, it is possible to state that salicylic acid, especially at doses above 0.50 mM, has negative effects on the germination and seedling growth parameters of psyllium.
