| Additional Information: | Capsicum sp are the commercially grown important food value plant well known for its pungency and pigment. An elicitor mediated improvement of the Capsaicinoids (pungency) and pigment (carotenoids etc) in fruits of Capsicum sp. on standing crop was studied. Three abiotic elicitors viz. methyl jasmonate, salicylic acid and ibuprofen at 0.5 to 2.5 µM concentrations were sprayed on to the fully opened flowers of Capsicum and the fruits were harvested during their ripening stage and analyzed for pungency and pigment content. The identification and analysis of the respective pungency and pigment contents were analyzed by HPLC. Methyl jasmonate at 2.5µM concentration enhanced capsaicin, dihydrocapsaicin and vanillyl amine production by 2.5 folds. Ibuprofen at 2.5 µM and 1.0 µM enhanced the both the pigments production i.e. Capsorubin and Capsanthin by 3-4 folds respectively. This elicitor mediated improvement of important metabolites of Capsicum sp i.e. pungency and pigments is having a lot of significance in view of their market value for these two metabolites. |
