Última Respiration rate and ethylene metabolism of ‘Jonagold’ apple and ‘Conference’ pear under regular air and controlled atmosphere Bragantia Saquet,Adriano Arriel; Streif,Josef. ABSTRACT The 1-aminocyclopropane-1-carboxylate (ACC) oxidase activity, ethylene production, CO2 release and O2 uptake of ‘Jonagold’ apple and ‘Conference’ pear were investigated during regular air and controlled atmosphere storage. Storage conditions tested at 0 °C during 6 months, with a further 10 d shelf-life in air at 20 °C were: 0.5 kPa O2 + 6.0 kPa CO2; 3 kPa O2 + 6 kPa CO2; 1 kPa O2 + 3 kPa CO2; 1.5 kPa O2 + 1.5 kPa CO2; 0.5 kPa O2 + 0.5 kPa CO2 and 2 kPa O2 + 1 kPa CO2. Apple and pear kept in regular air showed higher ACC-oxidase activity, ethylene production and respiration rates. Under controlled atmosphere, lower O2 and/ or higher CO2 partial pressures strongly inhibited ACC-oxidase activity and ethylene production of apple and pear. Agreeing...

The chlorophyll fluorescence technique was evaluated as a possible predictive and nondestructive method to detect low-O2 and/or high-CO2 injuries in 'Conference' pears and 'Jonagold' apples stored in controlled atmosphere (CA). The fruits were kept at 0°C in air, 1% CO2 + 2% O2 or 3% CO2 + 1% O2 during five months. Fluorescence parameters of minimal fluorescence (Fo), maximal fluorescence (Fm), and potential quantum yield - (Fm-Fo):Fm, also denoted as Fv:Fm- as well as the incidence of browning disorders were evaluated at several times during storage. No incidence of browning disorders was observed in 'Jonagold' apples, however, they showed a decrease in Fv:Fm during storage time with no differences between the CA-conditions. Air-stored apples showed a... Tipo: Info:eu-repo/semantics/article Palavras-chave: Fruits; Quality assessment; Physiological disorders.
