These parameters such as hormone ratio, culture medium type, light and temperature were optimized, and a high-performance liquid chromatography method for detecting CBD was established. The results showed that when the callus culture conditions were 1/2 MS + ZT 0.6 mg/L + IAA 0.4 mg/L, the induction rate reached a maximum of 97.47%, and the CBD content reached a maximum of 160.62 ± 0.32 μg/g. The correlation between hormone combination and the accumulation of secondary metabolites was revealed, and the key role of culture condition regulation in plant tissue induction and metabolite synthesis was confirmed. The research results provide a theoretical basis and technical support for efficient hemp breeding, industrial production of CBD and development and utilization of plant resources.展开更多
