    Author(s): Subhra Saikat Roy

    our study revealed the beneficial effect of melatonin, an indole amine hormone, on food value and storability of tomato. We have taken four doses of melatonin viz. 50, 100, 250 and 500 µmol/L. Two sprays were done at fruit setting and color break stage. Application of melatonin @ 250 µmol/L was found to be advantageous in improving the carbohydrate, protein, fat, total sugar and total soluble solids content in tomato fruits as compared to control (without melatonin). Melatonin application @ 250 µmol/L showed reduced activity of polygalacturonase-I (37.16%), polygalacturonase-II (39.40%) and ascorbic acid oxidase (35.14%) as compared to control; whereas maximum reduction of polyphenol oxidase activity (28.03%) was associated with melatonin (500 µmol/L). Melatonin application on phenolics, flavonoids, ascorbic acid and antiradical activity in tomato also shown in.. Read More»
