“…In some orchards, auxins are applied along with ethephon to avoid fruit drop. During postharvest, other products are also used to delay fruit ripening, such as 1-methylcyclopropene (1-MCP) (Fawbush et al, 2008(Fawbush et al, , 2009 and ethylene absorption sachets (ABS) (Brackmann et al, 2010;Corrêa et al, 2011). However, there is little information on the effect of these products on gas diffusion and on ethylene production, respiration rate, and physiological disorders of fruit after storage.…”

-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.

“…Several studies have demonstrated the effect of 1-methylcyclopropene (1-MCP), an ethylene action inhibitor, on ripening delay and control of plum internal browning (ARGENTA et al, 2003;CANDAN et al, 2006;CORRÊA et al, 2011). However, the 1-MCP has a high cost and a difficult application management to be implemented in MA storage.…”

ABSTRACT-Recent studies have shown that passive modified atmosphere storage (MA) delays the ripening of 'Laetitia' plums but it increases the incidence of internal browning in comparison to cold storage (CS), possibly due to high CO 2 and/or ethylene accumulation inside the package. The aim of this study was to evaluate the effect of active MA conditions [LDPE film (40 µm)] with CO 2 absorber combined with low ethylene (LE) on ripening and quality preservation of 'Laetitia' plums during storage at 0.5ºC±0.1ºC and RH of 96%±2%. The treatments evaluated were cold storage (CS; 21.0 kPa O 2 + <0.03 kPa CO 2 ); nonperforated MA with CO 2 absorber; non-perforated MA with CO 2 absorber and LE; perforated MA (with two perforations with diameter = 0.5 mm) with CO 2 absorber; and perforated MA with CO 2 absorber and LE. The partial pressures of O 2 + CO 2 (kPa) were 1.2 + <0.1 and 2.8 + <0.1, in non-perforated and perforated MA, respectively. Active MA, mainly non-perforated package, with CO 2 absorber and LE, delayed fruit ripening, but did not reduce the incidence of internal breakdown in 'Laetitia' plums cold stored for 60 days. Fruits in active MA, with perforated or non-perforated package, with CO 2 absorber and LE, showed lower intensity of internal breakdown than CS. Index terms: Prunus salicina, internal breakdown, ethylene, postharvest, ripening. MANUTENÇÃO DA QUALIDADE DE AMEIXAS 'LAETITIA' ARMAZENADAS EM ATMOSFETA MODIFICADA ATIVARESUMO -Trabalhos recentes têm demonstrado que a atmosfera modificada (AM) passiva retarda o amadurecimento de ameixas 'Laetitia', mas causa maior ocorrência de escurecimento da polpa do que o armazenamento refrigerado (AR), possivelmente devido ao acúmulo de CO 2 e/ou ao etileno no interior da embalagem. O objetivo deste trabalho foi avaliar o efeito da AM ativa, com absorção de CO 2 , combinada com baixo etileno (BE) sobre o amadurecimento e a manutenção da qualidade de ameixas 'Laetitia' durante o armazenamento a 0,5ºC±0,1ºC e UR de 96%±2%. Os tratamentos avaliados foram: AR (21 kPa de O 2 + 0,03 kPa de CO 2 ); AM + absorvedor de CO 2 ; AM + absorvedor de CO 2 e BE; AM com perfuração (duas perfurações de 0,5 mm de diâmetro) + absorvedor de CO 2 ; AM com perfuração + absorvedor de CO 2 e BE. Nos tratamentos com AM, foi utilizado o filme de polietileno de baixa densidade de 40 µm. As pressões parciais médias de O 2 + CO 2 (kPa) foram 2,8 + <0,1 e 1,2 + <0,1, em AM com perfuração e AM sem perfuração, respectivamente. A AM ativa, especialmente em embalagem não perfurada, com absorvedor de CO 2 e BE (<0,04 µL L -1 ), retardou o amadurecimento dos frutos, mas não reduziu a incidência de escurecimento da polpa após 60 dias de armazenamento. Os frutos acondicionados em AM ativa, em embalagem com ou sem perfuração, com absorvedor de CO 2 e BE, apresentaram menor intensidade de escurecimento da polpa do que em AR. Termos para indexação: Prunus salicina, escurecimento de polpa, etileno, pós-colheita, amadurecimento.1 .

“…Internal browning may be aggravated by the effect of ethylene (CANDAN; GRAEL; LARRIGAUDIÉRE, 2011;CORRÊA et al, 2011) and lower diffusion of O 2 and CO 2 gases through the flesh in stored fruits (BRACKMANN et al 2014). Thus, the use of complementary technologies to CA, such as 1-methylcyclopropene (1-MCP), induction of mass loss (IML) and low ethylene (LE) may be alternatives to reduce the occurrence and severity of internal browning.…”

“…Several studies have shown the effect of 1-MCP on ripening delay and post-harvest fruit quality maintenance (CANDAN; GRAEL; LARRIGAUDIÉRE, 2011;CORRÊA et al, 2011;MANGANARIS et al, 2008). Since internal browning in plums is aggravated by ethylene, 1-MCP may reduce its occurrence (CANDAN; GRAEL; LARRIGAUDIÉRE, 2011;CORRÊA et al, 2011). On the other hand, CA combined with LE may present similar effects to 1-MCP in 'Laetitia' plums.…”

Two experiments were conducted to evaluate the relative effects of controlled atmosphere (CA) associated with 1-methylcyclopropene (1-MCP; 1.0 μL L −1 ), induction of mass loss (IML; 2%), and low ethylene (LE; <0.04 μL L −1 of C 2 H 4 ) on the quality preservation of 'Laetitia' plums. In experiment 1 (2010), the treatments evaluated were cold storage (CS; 21.0 kPa O 2 + <0.03 kPa CO 2 ), CA1 (1 kPa O 2 + 1 kPa CO 2 ), CA1 + 1-MCP, CA1 + IML, and CA1 + LE. In experiment 2 (2011), the treatments evaluated were CS, CA2 (2 kPa O 2 + 2 kPa CO 2 ), CA2 + IML, and CA2 + 1-MCP. In both experiments, the fruit were stored at 0.5 ± 0.1°C and 96 ± 2% RH. CA storage delayed fruit ripening in both atmosphere conditions evaluated and reduced the internal browning of the 'Laetitia' plums, particularly in CA2. 1-MCP, LE, and IML had additional effects to CA1 on preserving flesh consistency. 1-MCP, irrespective of the CA condition, and IML, in CA1, reduced internal browning. CA1, regardless of the complementary technologies, reduced the incidence of decay and fruit cracking. Keywords: Prunus salicina. Internal browning. Physiological disorder. Ripening. AMEIXAS 'LAETITIA' ARMAZENADAS EM ATMOSFERA CONTROLADA COM INDUÇÃO DE PERDA DE MASSA E MANEJO DO ETILENO RESUMO -Foram conduzidos dois experimentos com o objetivo de avaliar o efeito da atmosfera controlada (AC) associada ao 1-metilciclopropeno (1-MCP; 1,0 μL L -1 ), à indução de perda de massa (IPM; 2%) e ao baixo etileno (BE; <0,04 μL L -1 de C 2 H 4 ) sobre a manutenção da qualidade de ameixas 'Laetitia'. No experimento 1, em 2010, os tratamentos avaliados foram armazenamento refrigerado (AR; 21 kPa O 2 + <0,03 kPa CO 2 ), AC1 (1 kPa O 2 + 1 kPa CO 2 ), AC1+1-MCP, AC1+IPM e AC1+BE. No experimento 2, em 2011, os tratamentos foram AR, AC2 (2 kPa O 2 + 2 kPa CO 2 ), AC2+1-MCP e AC2+IPM. Em ambos os experimentos, os frutos foram armazenados a 0,5±0,1 ºC e 96±2% de umidade relativa. A AC retardou o amadurecimento, em ambas as atmosferas avaliadas, e reduziu o escurecimento de polpa de ameixas 'Laetitia', especialmente na AC2. O 1-MCP, o BE e a IPM apresentaram efeito adicional à AC1 na manutenção da consistência da polpa. O 1-MCP, independente da condição de AC, e a IPM, na condição de AC1, reduziram o escurecimento da polpa.A AC1, independente do uso de tecnologias complementares, reduziu a incidência de podridões e de rachaduras.Palavras-chave: Prunus salicina. Escurecimento da polpa. Distúrbio fisiológico. Amadurecimento.
