“…Therefore, cell integrity loss may result in ethanol accumulation and in physiological disorders (Franck et al, 2007). However, there are evidences that the physiological disorders, in this case, is caused by low-energy production from the anaerobic metabolism, resulting in a low-defense mechanism (Pedreschi et al, 2009). Lower incidence of physiological disorders in these treatments also promoted higher cell wall integrity.…”

-The objective of this work was to evaluate the effect of growth regulators on gas diffusion and on metabolism of 'Brookfield' apple, and to determine their correlation with quality characteristics of fruit stored in controlled atmosphere. A completely randomized design was used with four replicates. After eight months of storage, the effects of water (control), aminoethoxyvinylglycine (AVG), AVG + ethephon, AVG + naphthaleneacetic acid (NAA), ethephon + NAA, sole NAA, 1-MCP, ethylene absorption by potassium permanganate (ABS), AVG + ABS, and of AVG + 1-MCP -applied at different rates and periods -were evaluated on: gas diffusion rate, ethylene production, respiratory rate, internal ethylene concentration, internal CO 2 content, mealiness, and intercellular space. Fruit from the control and sole NAA treatments had the highest mealiness occurrence. Growth regulators significantly changed the gaseous diffusion through the pulp of 'Brookfield' apple, mainly in the treatment AVG + ABS, which kept the highest gas diffusion rate. NAA spraying in the field, with or without another growth regulator, increased ripening metabolism by rising ethylene production and respiration rate, and reduced gas diffusion during shelf life. AVG spraying cannot avoid the ethephon effect during the ripening process, and reduces both the internal space and mealiness incidence, but it is not able to induce ethylene production or to increase respiration rates.Index terms: Malus domestica, aminoethoxyvinylglycine, ethylene absorption, fruit quality, 1-methylcyclopropene. Efeito de reguladores de crescimento na difusão de gases e no metabolismo de maçãs 'Brookfield' em armazenamento em atmosfera controladaResumo -O objetivo deste trabalho foi avaliar o efeito de reguladores de crescimento na difusão de gases e no metabolismo de maçãs 'Brookfield', e determinar sua correlação com características dos frutos armazenados em atmosfera controlada. Utilizou-se o delineamento experimental inteiramente casualizado com quatro repetições. Após oito meses de armazenamento, os efeitos de água (controle), aminoetoxivinilglicina (AVG), AVG + ethephon, AVG + ácido naftalenoacético (ANA), ethephon + ANA, somente ANA, 1-MCP, absorção de etileno por permanganato de potássio (ABS), AVG + ABS, e de AVG + 1-MCP -aplicados em diferentes doses e épocas -foram avaliados sobre: taxa de difusão de gases, produção de etileno, taxa respiratória, concentração interna de etileno, concentração interna de CO 2 , polpa farinácea e espaço interno. Frutos dos tratamentos controle e ANA sozinha apresentaram a maior ocorrência de polpa farinácea. Os reguladores de crescimento modificaram significativamente a difusão gasosa pela polpa de maçãs 'Brookfield', principalmente no tratamento AVG + ABS, que manteve a maior taxa de difusão de gases. A aplicação de ANA no campo, com ou sem outro regulador de crescimento, acelerou o metabolismo de amadurecimento, pelo aumento na produção de etileno e na taxa respiratória, e reduziu a difusão de gases durante a vida de prateleira.

“…GABA production is a hallmark signature of abiotic stress in plant vegetative and fruit tissues (Pedreschi et al 2009;Blanch et al 2012;Shelp et al 2012b). An association between temporal changes in GABA and the visual symptoms of CA-related injury was evident during elevated CO 2 storage at 38C.…”

“…Enhanced GABA levels occur in 1-MCP-treated 'Empire' apples within 15Á20 wk of storage at 38C, 2 kPa O 2 , 2 kPa CO 2 and coincide with onset of flesh browning (Lee et al 2012). Four to six months of CA storage (1 kPa O 2 , 10 kPa CO 2 , (18C) induce a significant metabolic difference between sound tissue and browning tissue in brown pears, with elevated concentrations of fumarate, threose, GABA, pyroglutamate, fucose, gluconate, trehalose and sucrose, and reduced concentrations of malate, erythritol and threitol (Pedreschi et al 2009). These changes can generally reflect the disturbed energy metabolism and a defective antioxidant system.…”

“…GABA is a major amino acid occurring in flesh tissues during developmental maturation of 'Honeycrisp' apples (Zhang et al 2010), and concentrations are elevated in brown flesh tissues of chilling-injured fruit (Leisso et al 2015). Elevated GABA levels have been reported for fruit of various strawberry cultivars that accumulate fermentative metabolites during CA storage (Deewatthanawong et al 2010a), and for disordered tissues of pears maintained under 1 kPa O 2 , 10 kPa CO 2 and (18C for 6 mo (Pedreschi et al 2009). Evidence is available for GABA accumulation in the early phase of CA storage when disorders are absent.…”

. 2015. Controlled atmosphere-related injury in 'Honeycrisp' apples is associated with g-aminobutyrate accumulation. Can. J. Plant Sci. 95: 879Á886. 'Honeycrisp' apples (Malus )domestica Borkh.), including fruit treated with the ethylene antagonist 1-methylcyclopropene (1-MCP), can be susceptible to controlled atmosphere (CA)-related injury of the flesh tissue during storage. To better understand the biomarkers associated with this physiological disorder, we compared the temporal responses of the universal stress signature, g-aminobutyrate (GABA), and visual symptoms of CA-related injury in apples subjected to elevated CO 2 . Fruit were treated with or without 1-MCP prior to CA [2.5 kPa O 2 , 5 (elevated) or 0.03 (ambient) kPa CO 2 ] storage at either 3 or 208C for up to 24 wk. At 208C, 1-MCP-treated apples displayed symptoms of CA-related injury by 3 wk of elevated CO 2 storage; a similar 15% disorder incidence was apparent by 6 wk in non 1-MCP-treated fruit. A maximal incidence of 30% for this disorder occurred after 24 wk at 38C in fruit held at elevated CO 2 , regardless of 1-MCP treatment. At 208C, GABA levels were 48% higher within 6 wk of the transfer of 1-MCP-treated fruit to elevated CO 2 . At 38C, a 2.6-fold increase in GABA level occurred by week 6 of elevated CO 2 storage, and was maintained for an additional 18 wk thereafter; a similar change in GABA level was apparent in non 1-MCP-treated fruit, albeit delayed until week 18 of storage. These findings indicate that shifts in GABA are associated with the onset of visual symptoms of CA-related injury in 'Honeycrisp' fruit in response to elevated CO 2 , regardless of 1-MCP.Key words: g-aminobutyrate, apple, controlled atmosphere, controlled atmosphere-related injury, 1-methylcylopropene Chiu, G.
