Absorção de 1-metilciclopropeno aplicado em maçãs 'Royal Gala' armazenadas em atmosfera refrigerada juntamente com madeira

Postharvest quality of ‘Baigent’ apples as a function of single and multiple preharvest spray aminoetoxivinylglycine and ethephon applications

“…According to Brackmann et al (2004), the rapid loss of quality of 'Gala' apples stored under refrigeration is linked to the high ethylene production rates, in addition to the high respiratory rate of this cultivar. The higher the ethylene production and action, the higher the ripening speed and fruit senescence (BRACKMANN et al, 2009b).…”

Extremely low-oxygen storage: aerobic, anaerobic metabolism and overall quality of apples at two temperatures

“…Each treatment was composed of four replicates of 25 fruit and the design was completely randomized. For 'Royal Gala' apples, 4 treatments were carried out in a factorial scheme (2 × 2), with two atmosphere conditions: [1] 1.2 kPa O 2 + 2.0 kPa CO 2 ; [2] 0.8 kPa O 2 + 1.6 kPa CO 2 ; and two temperatures (1.0 and 1.5 °C) (Both et al 2017;Brackmann et al 2009). For 'Galaxy' apples, a bifactorial scheme (3 × 2) was used, with three atmosphere conditions [1] 1.2 kPa O 2 + 2.0 kPa CO 2 ; [2] 0.8 kPa O 2 + 1.6 kPa CO 2; [3] 0.4 kPa O 2 + 1.2 kPa CO 2, and two temperatures (1.0 and 1.5 °C).…”

“…Most apples produced in Brazil belong to the 'Gala' cultivar and its spontaneous mutants, including 'Galaxy' and 'Royal Gala' , totalizing a production of 326,658 t in 2017/2018 crop, representing 66% of the national apple production (Agapomi 2018). These mutants stand out for presenting a good red coloration of epidermis (Brackmann et al 2009(Brackmann et al , 2012Weber et al 2013), high juiciness and better balance between acidity and soluble solids (Thewes et al 2015).…”

“…The reduction in temperature suppresses the respiratory pathway, ethylene production and, consequently, the reduction of biochemical changes in the fruit (Kruse et al 2011;Saltveit 1999;Steffens et al 2007). The ideal temperature for controlled atmosphere storage of 'Gala' apples and their mutants ranges from 0.0 to 1.0 °C (Both et al 2017;Brackmann et al 2009;Thewes et al 2017a). However, recent studies reported the possibility of increasing the storage temperature of some types of apples without quality losses (Anese et al 2019;Weber et al 2019).…”
