摘　　要：该文研究茉莉酸甲酯(methyl jasmonate,MJ)对颠茄毛状根的逆境生理指标及莨菪碱、东莨菪碱含量的影响.结果表明,MJ的加入对颠茄毛状根生长具有一定的抑制作用,MDA、脯氨酸、可溶性蛋白质含量均有不同程度的变化:增加或先增加后降低;3种保护酶(SOD,POD,CAT)活性变化与诱导浓度有关;30μmol/L的MJ处理组东莨菪碱含量最高,10μmol/L的MJ处理组莨菪碱含量最高.表明MJ能显著促进颠茄毛状根中生物碱成分的积累.To study the effects of methyl jasmonate（MJ）on physiological indexes and accumulation of main tropane alkaloids in Atropa belladonna L.hairy roots,MJ was added in different concentrations to the medium.The results showed that MJ treatments inhibited hairy root growth,and the contents of soluble protein,MDA and pro increased in different extends or first increased and then decreased.Changes in the activity of the three protective enzymes（SOD,POD and CAT）was associated with the induction concentration.The highest accumulation of scopolamine and hyoscyamine was observed in the treatments of30μmol/L and 10μmol/L MJ,respectively,thus indicating that MJ could significantly promote the accumulation of secondary metabolites in A.belladonna hairy roots.
