SALICYLIC ACID-INDUCED MODULATION OF GROWTH AND METABOLISM OF A MEDICINAL PLANT MENTHA SPICATA L.Abstract
Salicylic acid is a phenolic plant growth regulator found in plants with various important physiological roles. This investigation was aimed to study the effect of exogenous application of salicylic acid on the growth, metabolism and health status of Mentha spicata, an aromatic medicinal plant having several monoterpenes and antioxidants which show various kinds of medicinal properties. In the present work, some growth and biochemical parameters were recorded at 30 and 60 days after treatment with different concentrations of salicylic acid (0, 100, 200 and 300 µg ml-1). Results clearly revealed that salicylic acid particularly at 200 µg ml-1 concentration significantly enhanced most of the growth and some of the biochemical attributes as well as the antioxidant property when compared with that of control plants. It can be concluded that exogenously applied salicylic acid at particular doses can enhance the biomass production as well as the medicinal potential of M. spicata as evidenced from some reliable physiobiochemical parameters.
