“…Application of 1-MCP extends shelf life of a number of avocado cultivars including 'Ettinger', 'Fuerte', 'Reed' (Feng et al, 2000), 'Hass' (Hofman et al, 2001), 'Simmonds' (Jeong et al, 2002) and 'Pinkerton' (Hershkovitz et al, 2005). According to those studies, the effectiveness of 1-MCP treatment depended upon the 1-MCP concentration used, duration of exposure to 1-MCP, cultivar studied and temperature under which avocados were stored.…”

“…'Pollock' fruits for a significantly longer period. This can be attributed to reduction in chlorophyllase enzyme activity, which regulates the loss of green colour, in many avocado cultivars including 'Hass', 'Pinkerton' and 'Ettinger' (Hershkovitz et al, 2005). 1-MCP treated 'Pollock' fruits retained their glossiness significantly longer than non-treated fruits remaining unchanged until the end of shelf life (10 days after harvest), another quality affecting consumer preference.…”

“…Although many avocado cultivars such as 'Ettinger', 'Hass', 'Pinkerton', 'Simmonds' and 'Beta', have been tested for the effect of 1-MCP on the ripening-related changes in fruit (Feng et al, 2000;Hofman et al, 2001;Jeong et al, 2002;Hershkovitz et al, 2005), its effects on cv. 'Pollock' is unknown.…”

ABSTRACT1-MCP is a competitive, gaseous ethylene inhibitor, which binds irreversibly to ethylene receptors and thereby blocks effects of ethylene in plants. The potential for 1-MCP to delay ripening in avocado cv. 'Pollock' fruit was examined under tropical ambient storage conditions. Fruits harvested at commercial maturity were exposed to 300 nll -1 1-MCP gas for 20 h under 27± 2 ˚C and then stored under ambient conditions (27± 2 ˚C and relative humidity 65 ± 2%). Fruits were assessed daily for fresh weight, firmness, skin colour, fungal rot development and glossiness. The antifungal activity in diethylether extracts of fruit peel was assessed through thin layer chromatography (TLC) coupled with Cladosporium bioassay. Exposure to 1-MCP extended the shelf life up to 9 days of fruit by 2.2 fold as compared to the shelf life of 4 days of the controls. Stem end rot caused by Botryodiplodia theobromae was found to be the shelf-life determining factor of the fruits. 1-MCP treatment resulted in a significant (p< 0.05) delay in change in peel colour, softening and glossiness of fruit as compared to the controls. Bioassays using Cladosporium fungus revealed the presence of antifungal activity at Rf 0.75 in both 1-MCP treated and control fruits. 1-MCP treatment was effective in delaying the decline of antifungal activity in fruit apparently along with the delay of other ripening-related changes and minimizing losses encountered during storage under warmer ambient conditions.

“…Em peras 'Abbé Fétel', Zerbini et al (2005) observaram atraso no amarelecimento dos frutos tratados com 1-MCP. Em abacate, Hershkovitz et al (2005) observaram menores valores de L e C nos frutos submetidos à aplicação de 1-MCP. Porém, nessa espécie, respostas distintas têm sido relatadas (Hofman et al, 2001).…”

“…Estudos com diferentes frutos apontam a retenção da firmeza como a mais importante resposta associada ao 1-MCP (Amodio et al, 2005;Hershkovitz et al, 2005;Laamin et al, 2005;Zerbini et al, 2005). Essa resposta permite estender o período de armazenamento e a vida útil sob temperatura ambiente em ameixas e damasco, por exemplo (Valero et al, 2005).…”

RESUMO -Avaliou-se a influência da época de aplicação pós-colheita do 1-metilciclopropeno (1-MCP) e do frigoarmazenamento sobre a vida útil de mangas 'Tommy Atkins', colhidas em estádio de maturação 2 (casca de cor verde-clara no ápice do fruto e polpa levemente amarela próximo à semente). Para estudo da época de aplicação, foram comparados: controle, aplicação apenas no início do armazenamento refrigerado e aplicação apenas no final da refrigeração. Os frutos foram expostos a 1.500 nL.L -1 de 1-MCP durante 12 horas. As avaliações foram realizadas aos 0; 7; 15; 18; 20; 21 e 22 dias, sendo que até o décimo quinto dia os frutos estiveram sob refrigeração (10,6ºC ± 3,6 e 84% UR ± 7) e, em seguida, foram transferidos para temperatura ambiente (24,4ºC ± 2,9 e 42% UR ± 11). O delineamento experimental foi inteiramente casualizado, em fatorial 3x7 (época de aplicação de 1-MCP x tempo de armazenamento), com quatro repetições. O aumento do croma e a redução no ângulo de cor da casca foram mais graduais nos frutos tratados com 1-MCP no final da refrigeração. A aplicação no início da refrigeração atrasou temporariamente o decréscimo na acidez titulável. O amaciamento da polpa ocorreu mais lentamente, até o sexto dia após a saída da câmara fria, nos frutos que receberam 1-MCP, independentemente da época de aplicação. Contudo, aos 22 dias, essas diferenças não eram mais reconhecidas. Registrando-se equivalência entre as duas épocas de aplicação, a opção pelo tratamento no início da refrigeração resulta em menor interferência nas operações pós-colheita atualmente praticadas. Termos para Indexação: amadurecimento, firmeza da polpa, inibidores de etileno, vida útil. POSTHARVEST PERIOD FOR 1-METHYLCYCLOPROPENE APPLICATION AND COLD STORAGE ON SHELF LIFE OF 'TOMMY ATKINS' MANGO FRUITABSTRACT -It was evaluate the influence of the application period of 1-methylcyclopropene (1-MCP) and cold storage on post harvest conservation of 'Tommy Atkins' mango fruit, harvested at maturity stage 2 (light green skin color at the top of the fruit and lightly yellowish pulp next to the seed). To study the application period, it was compared: control, application only on the beginning of refrigerated storage and application only at the end of refrigerated period. Fruits were exposed to 1.500 nL.L -1 of 1-MCP during 12 hours. The evaluations were done at 0, 7, 15, 18, 20, 21 and 22 days, being kept at refrigeration (10.6ºC ± 3.6 and 84% RH ± 7) until the fifteenth day, when they were transferred to ambient temperature (24.4ºC ± 2.9 and 42% RH ± 11). The experimental design was completely randomized, in a 3x7 (time of 1-MCP application x time of storage) factorial arrangement, with four replications. The increase on chroma and the reduction on Hue angle of skin were more gradual on fruits treated with 1-MCP at the end of refrigeration. The application on the beginning of refrigeration delayed temporarily the decrease on titratable acidity. The pulp softening was slower on fruits treated with 1-MCP until the sixth day after the transfer from storage c...
