Calvo, Gabriela Candan, Ana Paula Pears Ethylene Maturity Concentrating Pera Etileno Madurez Concentración 1-Methylcyclopropene 1-MCP 1-Metilciclopropeno Trabajo presentado al IV International Conference Postharvest Unlimited 2011. Leavenworth, Washington (Estados Unidos), Mayo 2011 ‘Williams’ pear (Pyrus communis L.) is the most important cultivar grown in Alto Valle of Rio Negro, Argentine. 1-methylcyclopropene (1-MCP) proved to be highly effective in inhibiting ethylene action and maintaining postharvest quality. However, due to logistical problems the commercial application of 1-MCP is often delayed, which may reduce the efficiency of this treatment. In this study we determined the influence of 0.3 and 0.6 ml L-1 of 1-MCP applied after 0, 3, 7 and 10 days at 0°C on the post harvest quality of early and late harvested ‘Williams’ pears. Untreated fruit was used as control. After 60 and 90 days of storage at -0.5°C, ethylene production and maturity indexes (flesh firmness, soluble solids, acidity, starch degradation, epidermis color), were measured. The results showed that all 1-MCP treatments significantly reduced ethylene production and fruit ripening irrespective of the delay period. The ethylene production of fruits was undetectable during the delay period at 0°C, meaning that ethylene was not affected by time at 0°C. Moreover, no differences were observed between 1-MCP concentrations, with 0.3 ml L-1 sufficient to reduce ethylene production and ripening even in late harvested fruits. We hypothesize that the temperature during the delay period plays a key role on the maintenance or reduction of 1-MCP efficacy. It is important to emphasize, that the results obtained under experimental conditions may not be directly extrapolated to a commercial-scale, since there are other factors that could reduce the effectiveness of 1-MCP treatments.
