Growth, secondary metabolites production, antioxidative and antimicrobial activity of mint under the influence of plant growth regulators

摘要

The effects of plant growth regulators on Mentha piperita explants culturedin vitro were studied for the purpose of analyse growth, secondary metabolite production,antioxidant and antimicrobial activities in micropropagated plants. The basal medium wasexperimentally supplemented with the auxin, indole-3-butyric acid (IBA) and the cytokinin, N6-benzyladenine (BAP) individually and in combination. Treatment with BAP and IBA resulted inan increased shoot and root number. The production of phenolic compounds was affected bythe addition of the highest concentration of BAP, while antioxidant and antimicrobial activitieswere affected by several BAP and IBA treatments. Our results demonstrate that the applicationof growth regulators increases growth and secondary metabolite productions in the medicinalherb M. piperita.
