Background : Scrophularia koraiensis is a herbaceous perennials belonging to the family Scrophulariaceae. This study was carried out to survey the effect of LED on root develop characteristics in Scrophularia koraiensis seedling. Methods and Results : Seeds were collected from plants growing in the Mt. Kariwang Jeongseon, Gangwon-do in September 2014, and they were sown to 128 cell plug tray filled with Peatmoss (TKS-2) soil at March, 2015. The experiment was performed with three different LED (Blue, Red, Blue + Red) at July, 2015. Morphological characteristics of root (total root length, root projet area, root surface area, root diameter and root volume) were analyzed with WinRHIZO software. Seedling root growth of scrophularia koraiensis was surveyed to be the highest at the Blue + Red LED in all measuring. Total root length was measured high in the order of Blue + Red, Red, Blue LED. Conclusion : According to the results, Scrophularia koraiensis seedling showed the highest root growth in Blue + Red LED.
