Abstract :Lavender is a valuable ornamental and aromatic plant species with several applications, including food additives, cosmetics, perfumes, medicine, and aromatherapy, owing to its antimicrobial, antibacterial, antiviral, and antioxidant properties, as well as its pleasant odor. The purpose of this study was to determine the rooting capability of lavender species insert ignore into journalissuearticles values(Lavandula angustifolia and Lavandula × intermedia); in different media insert ignore into journalissuearticles values(peat, perlite, peat+perlite); and different doses of indole-3-butyric acid insert ignore into journalissuearticles values(IBA); insert ignore into journalissuearticles values(1000, 1500, and 2000 ppm); on cuttings. After 5 seconds in the insert ignore into journalissuearticles values(IBA); solution, the cuttings were planted in various rooting media in the greenhouse environment. The highest rooting rate, 93%, was obtained from 2000 ppm IBA application in peat+perlite insert ignore into journalissuearticles values(1:1); medium, whereas the lowest rooting rate, 13%, was obtained from Lavandula angustifolia species from control application in peat media. In a peat+perlite insert ignore into journalissuearticles values(1:1); medium with 1500 ppm, the longest root length was 13.16 cm. IBA application Lavandula angustifolia species, the lowest root length in Lavandula × intermedia cuttings were 2.7 cm from control application in perlite medium. Lavandula × intermedia cuttings in peat medium produced the best results in terms of root number insert ignore into journalissuearticles values(3.36 pcs/cuttings);, while Lavandula × intermedia cuttings in perlite medium produced the lowest root number in the control application. In terms of viability rate, both species received high values, with the lowest viability rate obtained from the control application in perlite medium with 80% in Lavandula angustifolia species.
