| dc.description.abstract | The present investigation was aimed at evaluation of twenty-five tomato genotypes (PLRT-1 to PLRT-25) along with one check variety (Punjab Ratta) to estimate lycopene, carotene, vitamin A, vitamin C, acidity and tomatine for selection of best five genotypes. PLRT-8, PLRT-10, PLRT-15, PLRT-20 and PLRT-22 were found to be the best five genotypes on the basis of lycopene content using the test of Tukey HSD (SPSS 16.0). Selected genotypes were analyzed for total antioxidant capacity and plant hormones (indole-3-acetic acid, gibberellin and abscisic acid) from plant parts (root, stem and leaf) at monthly intervals. An increase was observed in total antioxidant capacity of root, stem and leaf as the months passed. During development, the gibberellin content increased till the month of April and then plummeted in the month of May in root, stem and leaf tissues. An increase in indole-3-acetic acid content was reported in root, stem and leaf as the months passed. During development, the abscisic acid content increased gradually in root, stem and leaf tissues. The correlation of antioxidant capacity and plant hormones with lycopene content was worked out. Significantly positive correlation between antioxidant capacity and lycopene was observed in root, stem and leaf tissues. Significantly positive correlation between gibberellin and lycopene was noticed in stem and leaf, however in roots there was no significant correlation. Indole-3-acetic acid and abscisic acid showed no significant correlation with lycopene in root, stem and leaf tissues. | en_US |
