“…However, according to the correlation analysis, the high respiration rate may be related to the ethylene production. This fact has been pointed out by previous researchers (Brackmann et al, 2010;Pinto et al, 2012;Sen et al, 2012). Fruit showed a higher respiration rate in control treatment than in the other ones, after six days of shelf life.…”

-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.

“…It varies according to the cultivar, storage temperature, mass loss, and atmosphere type in which fruit are stored Steffens et al, 2007;Pinto et al, 2012). In the present study, however, the respiration rate was also influenced by the growth regulators and the days of shelf life (Table 2).…”

“…However, fruits with boron showed higher levels of soluble solids ( Figure 2G) due to the higher metabolism of fruits submitted to this treatment, leading in cell wall degradation ( Figure 2C and D). Similar results were obtained in 'Royal Gala' apples (BRACKMANN et al, 2007) and peaches (PINTO et al, 2012).…”

“…It may also be the result Almeida et al 4055 of the difference in nutrient availability between the systems, the culture management in the systems and the lowest temperature in the conventional, when compared to hydroponics. A fact that was also confirmed by Pinto et al (2012) while they studied the induction of weight loss in postharvest quality of 'Eragil' peaches was an increase in firmness with an increase in mass loss. Hoppula and Karhu (2006) observed that the low firmness in the strawberry is strongly related to high temperatures.…”

The strawberry is highly perishable, has high metabolic activity and considerable levels of favorable substrates for proliferation of pathogenic organisms, such as humidity, organic acids and sugars. These organisms lead to further, therefore reducing post-harvest shelf-life. With this in mind, the research objective was to evaluate the post-harvest shelf life in cooled storage of two cultivars of strawberries (Oso Grande and Festival) in the hydroponic cultivation system in coconut fiber substrate, and then compare them with the quality obtained in conventional farming. The strawberries were stored under refrigeration (2 ± 2°C and 85% ± 10%) using modified atmosphere, with 9 µ PVC film for 14 days. The experiment was conducted in a completely randomized design, distributed in a sub-subdivided plot with the cropping systems in the plot, cultivars in the subplot and in the sub-subplot with storage times of 0, 3, 6, 10 and 14 days with three replicates. The use of cooling associated with modified atmosphere increased the shelf-life of the strawberries of both systems, indicating the potential of this combination to maintain the post-harvest quality of the fruit. Although the shelf life of cultivars of both systems increased, the fruits produced in the conventional system showed better physical-chemical characteristics.
