MARTIN, Mariuccia Schlichting de et al. Storage potential of ‘SCS426 Venice’ apples under different storage technologies. Rev. Bras. Frutic. [online]. 2018, vol.40, n.2, e-631.  Epub 09-Abr-2018. ISSN 0100-2945.  http://dx.doi.org/10.1590/0100-29452018631.

This study aimed to evaluate the storage potential of SCS426 Venice apples under different storage technologies. Fruits were harvested in an experimental orchard located in Fraiburgo, SC and stored for up to eight and ten months in 2013 and 2014, respectively. Apples were treated or not with methylcyclopropene (1-MCP) and stored under air atmosphere (AA, 0.5±0.5 °C/RH 85±5%) or controlled atmosphere (CA; 1.5 kPa of O2 and 1.5 kPa of CO2 at 0.7±0.5 °C/RH of 93±3%). Fruits were evaluated every two months of storage, after one and seven days of shelf life (23 ± 0.3 °C/RH 93±3%). The storage period of ‘SCS426 Venice’ apples under AA without 1-MCP application should not extend beyond six months. Under this storage condition, fruits had higher incidence of decay, ethylene production and respiratory rates, higher skin degreening, lower flesh firmness, titratable acidity and soluble solids content than fruits stored under CA or AA with 1-MCP. ‘SCS426 Venice’ apples develop flesh browning and superficial scald after long-term storage. ‘SCS426 Venice’ apples under AA treated with 1-MCP or under CA (regardless of 1-MCP application) can be stored for more than eight months, keeping flesh firmness above 14 lb and low incidence of physiological disorders even after ten months of storage.
