Özet
<p>Abstract</p><p>The Lamiaceae family comprises herbaceous to woody plants that can thrive in a wide range of habitats and are cosmopolitan</p><p>in distribution. In Turkey, there are 45 genera and 586 species belonging to the Lamiaceae family. Among these species, 239</p><p>taxa are endemic, making it the third-largest family in Turkey in terms of endemic individuals. In this study, seeds of three</p><p>species from the Lamiaceae family, Izmir oregano (Origanum onites L.), French lavender (Lavandula stoechas L.), and basil</p><p>(Ocimum basilicum L.), were used as test materials. The research aimed to overcome heterogeneous and low germination</p><p>issues observed in these seeds, which were determined to be seed-related through preliminary studies, and to achieve the</p><p>highest germination percentage and average germination time. Various pre-sowing treatments were applied to improve the</p><p>germination performance and quality of Izmir oregano, French lavender, and basil seeds. For this purpose, the effects of</p><p>treatments including control, KNO3, GA3, polymer coating, priming, priming + polymer coating, priming + polymer coating</p><p>+ KNO3, and priming + polymer coating + GA3 on seed germination rate and average germination days were investigated</p><p>in comparison to the control. Prior to the treatments, molecular analyses were conducted on all seed samples to detect viral</p><p>agents. As a result of the research, the highest germination percentage of 94% was found in Izmir oregano with the priming</p><p>+ polymer coating + KNO3 treatment. In contrast, for French lavender and basil seeds, the germination performance with</p><p>a 92% and 94% germination rate, respectively, was achieved with the priming + polymer coating + GA3 treatment. Molecular</p><p>analyses conducted on seed samples did not detect any viral agents.</p><p>Keywords Lamiaceae · Priming · Seed treatments · Germination · Virus · qPCR</p>
