THE The effect of plant defence elicitor on Costus igneus for the enhanced phytochemical productivity
Medicinal Plants have proven potential of treating and preventing various disorders and illness from the ancient time. Many Phytopharmaceuticals companies are emerging as a result of its popularity in both the developed as well as developing countries. Newer approaches are developed to protect the plant source and to enhance its productivity in terms of phytochemicals so that the demand and supply can be balanced. Costus igneus, a newer plant to India is gaining its popularity for its use as ornamental plant in southern part of the country to Diabetes treatment herbal remedy. Flavonoid diglycosides and sapogenins are mostly responsible for its anti-diabetic activity. Due to over exploitation of plant some alternative methods has to be developed in order to protect the plant from its natural habitat. Elicitors are the compounds that stimulating plant defence pathways and the secondary metabolites are released due to defence responses which are triggered and activated by elicitors. The present study was focused on the application of Salicylic acid (SA) as an elicitor in different concentration (0.50 mg/l, 0.100 mg/l, 0.150 mg/l), which was sprayed on the plants of Costus igneus grown using complete block design in controlled growth conditions provided in polyhouse and the quantitative estimation for phytochemicals was done. The results suggest that SA enhances the quantity of desired phyto pharmaceuticals, which also plays as essential role in plant defensive pathways.
