Abstract

Pêssegos cv. Flordaprince foram armazenados a 1 ± 1oC e 85-90% de umidade relativa, em diferentes tipos de embalagens plásticas, por períodos de 14 e 28 dias. Os tratamentos envolveram o uso de filme de PVC, polietileno de alta densidade, polietileno de baixa densidade e o controle (sem embalagem). As frutas desta cultivar puderam ser armazenadas por 14 dias, enquanto que aos 28 dias houve alta incidência de injúria pelo frio ("lanosidade"). O uso das embalagens plásticas reduziu a perda de peso durante o armazenamento refrigerado. O polietileno de baixa densidade manteve mais alta a firmeza de polpa das frutas durante o período de refrigeração.<br>Peaches cv. Flordaprince were stored at 1 ± 1oC and 85-90% relative humidity, in different plastic packings, for periods of 14 and 28 days. The treatments were: PVC film, high density polyethylene, low density polyethylene and the control (without packing). It was verified that fruits of this cultivar supported storage for periods of 14 days, while after 28 days of cold storage there was a high incidence of chilling injury ("woolliness") in fruits. The use of plastic packings reduced the weight loss during cold storage. The low density polyethylene maintained the pulp firmness higher during the refrigeration period
