摘　　要：甘草细胞悬浮培养体系中添加10 mg·L^(-1)水杨酸可促进和提高甘草细胞的生长和甘草总黄酮产量。添加水杨酸可导致细胞中过氧化氢含量升高,引起细胞中苯丙氨酸裂解酶、过氧化氢酶和过氧化物酶活性的增强以及丙二醛含量的升高。Effects of salicylic acid on the cell biomass and flavonoid accumulation in cell suspension cultures of Glycyrrhiza inflata were studied. The results showed that 10 mg·L^-1 salicylic acid increased the cell biomass and flavonoid accumulation by 28% and 33%, respectively. In addition, salicylic acid increased the content of H2O2, the activities of phenylalanine ammonialyase, catalase, peroxidase and malondialdehyde content.
