Background : This study was conducted to developed the propagation method by cutting for mass cultivation of Vitex roundifolia. We were pitched the cutting two times and treated plant growth regulators to enhance the rooting percentage. Vitex roundifolia is live in beach sandy soil south of Hwanghae-Do and Gangwon-Do. Vitex roundifolia have been used to bath foam. It is good for aromatic plant. It has 0.8% essential oil content in leaf and flower. Major components of essential oil were alpha-Pinene, Sabinene, beta-Pinen, 1,8-cineole, d-Limone. Despite the superior usability, it had not yet been made by the artificial cultivation Methods and Results : We were pitched the cutting of a first-year branch on June 5, which was greenwood cutting and July 17, which was semi-hardwood cutting at Kwangseung-ri beach, Gochanggun, Jeonbuk. The length of cutting was 10cm. It had 3~4 nodes, we stuck a cutting remain 2 nodes above ground on ordinary raise seedling soil. Rooting percentage was measured at 60 days after stuck a cutting. Rooting percentage was higher greenwoody cutting(95%) than semi-hardwood cutting(57.6%). In green wood cutting, there was no significance with plant growth, but chemical injury was occurred in IBA 5,000ppm. In semi-hardwood cutting, there was significance with plant growth regulators. The rooting percentages of all the treat were higher than control(no treatment). Rooting percentage was the highest in NAA 5,000ppm treated. Conclusion : Greenwood cutting method was more proper to propagation for Vitex roundifolia than semi-hardwood cutting. The optimum time to cutting for Vitex roundifolia propagation was the early in June. If miss a time to propagation Rooting percent was elevated by plant growth regulator.
