Methyl jasmonate does improve postharvest conservation of ‘Golden’ papaya fruit

ABSTRACT: Methyl jasmonate (MeJA) is recognized as a plant hormone that induces several biochemical changes related to improving fruit quality, but it evident the effect of MeJA during postharvest very variable upon concentration, species, and even cultivars. The objective this research was relate application regulator at low concentration (10 µmol L-1 for 24 h) in physiology, on incidence anthracnose quality ‘Golden’ papaya storage ± 1°C. From seventh day storage, reduced by more than 50% with treatment. lesion area after infection also reduced. Although, acidity, ascorbic acid soluble solids content were not altered hormonal skin color pulp firmness showed slight retention. reduction ethylene production accompanied respiration treated fruits. MeJa increased CAT activity only whereas SOD induced both pulp. increase from third may have contributed lipid peroxidation skin, MDA cannot be explained activity. In summary, severity anthracnose, decreased respiration, peroxidation. It concluded L-1) contribute control ´Golden`papaya slows ripening
