Abstract: In this paper, the callus subculture and its darkening control of Eucommia ulmoides were investigated. The results indicated that B5+0.5 mg/L NAA +1.0 mg/L 6-BA is the optimum medium for callus subculture and darkening control. It was the most efficient anti-darkening treatment that the 0.5% activated charcoal (AC) was added in base medium. Compared with high intensity light and red light, the callus growing under blue light or dark showed the lighter darkening.
