In recent years, C. nitidissima planting area has been increasing, resulting in the growing gap between the supply and demand of C. nitidissima seedlings. At present, C. nitidissima can be propagated through seeding, cutting, grafting, plant tissue culture and air layering. Among them, cutting and tissue culture are the most commonly used methods for rapid propagation of C. nitidissima. Optimal rooting medium, type and concentration of hormones and environmental conditions are critical factors for C. nitidissima propagation by cuttings, while detoxification and optimization of medium composition are important for C. nitidissima propagation by tissue culture.
