Aminoethoxyvinylglycine: isolated and combined with other growth regulators on quality of ‘Brookfield’ apples after storage Scientia Agricola
Brackmann,Auri; Thewes,Fabio Rodrigo; Anese,Rogerio de Oliveira; Both,Vanderlei; Linke Junior,Wanderlei; Schultz,Erani Eliseu.
Growth regulators are used in the production of apples worldwide, especially to extend the harvest period and maintain postharvest quality. This study aimed to investigate the effects of applying aminoethoxyvinylglycine (AVG) in isolation as well as in combination with other growth regulators and postharvest techniques on the harvest quality and storage potential of ‘Brookfield’ apples (Malus domestica), a ‘Gala’ strain. Fruit receiving AVG only had the highest starch content and the highest titratable acidity at harvest. After 8 months of storage, the AVG + 1-MCP (1-methylcyclopropene) and AVG + ABS (ethylene absorption) conserved higher flesh firmness than to all the other treatments. Naphthaleneacetic acid (NAA) application induced ACC oxidase enzyme...

Controlled atmosphere maintains native and cultivated yerba mate quality during shelf life after long-term storage Bragantia
Thewes,Fabio Rodrigo; Brackmann,Auri; Schultz,Erani Eliseu; Machado,Eduardo Perkovski; Ludwig,Vagner; Santos,Luana Ferreira dos.
ABSTRACT Yerba mate shows social and economic importance for the Southern Latin American countries due to its easy production and large market range. However, there is a problem to harvest the yerba mate at the correct period and to store it until processing and marketing. Thus, the aim of this paper was to evaluate the interaction among the storage in controlled atmosphere, effect of cultivation form and shelf life period on yerba mate quality after long-term controlled atmosphere storage. The experiment was conducted in a factorial arrangement (3 controlled atmosphere conditions × 2 cultivation forms × 4 weeks of shelf life). Native yerba mate, stored under controlled atmosphere, showed higher chlorophyll concentration as compared to the cultivated one....

Extremely low oxygen partial pressures for the storage of ‘Royal Gala’ apple Bragantia
Berghetti,Magno Roberto Pasquetti; Brackmann,Auri; Thewes,Fabio Rodrigo; Schultz,Erani Eliseu; Ludwig,Vagner; Wendt,Lucas Mallmann; Thewes,Flavio Roberto; Schmidt,Suele Fernanda Prediger.
ABSTRACT The aim of this study was to evaluate the effect of storing ‘Royal Gala’ apple under extremely low oxygen partial pressures on their anaerobic metabolism, ethylene production and fruit quality after 9 months of storage plus 7 days of shelf life at 20 °C. The storage conditions tested were: 1.2 kPa O2 + 2.0 kPa CO2; 0.7 kPa O2 + 1.5 kPa CO2; 0.5 kPa O2 + 1.2 kPa CO2; 0.4 kPa O2 +1.2 kPa CO2 and 0.25 kPa O2 + 0.0 kPa CO2. The fruit storage temperature was 1.0 °C (± 0.1). Fruit stored at 0.4 kPa O2 + 1.2 kPa CO2 maintained higher flesh firmness and a higher percentage of healthy fruit. The fruit stored under the 0.25 kPa O2 + 0.0 kPa CO2 condition had lower flesh firmness as well as a reduced percentage of healthy fruit and a high production of...

Postharvest quality of ‘Brookfield’ apple field-treated with naphthalene acetic acid alone or combined with other growth regulators Bragantia
Wendt,Lucas Mallmann; Brackmann,Auri; Both,Vanderlei; Thewes,Fabio Rodrigo; Schultz,Erani Eliseu; Ludwig,Vagner; Berghetti,Magno Roberto Pasquetti.
ABSTRACT The Gala cultivars represent about 65% of the Brazilian apple production, however, it has a short harvest period, making necessary to use technologies that anticipate or delay fruit maturation. A widely used technology is the preharvest application of growth regulators. The objective of this investigation was to evaluate the effect of preharvest application of naphthalene acetic acid (NAA) combined with aminoethoxyvinylglycine (AVG) and 2-chloroethylphosphonic acid (Ethephon), on the quality of ‘Brookfield’ apple at harvest and after eight months controlledatmosphere (CA)(1.2 kPa O2 and 2.0 kPa CO2) storage followed by seven days of shelf life at 20 °C. The treatments were: [1] Control: application of water only; [2] NAA (40 g.ha-1); [3] NAA (40...
