“…This result shows that even in the absence of exogenous ethylene, 1-MCP was efficient in prolonging the conservation of the ornamental pepper plants. Simulating transportation conditions in Brazil, Cavatte et al (2013) observed that the fumigation of the ornamental pepper plants with 1 μL L -1 of 1-MCP prevented chlorophyll and carotenoid degradation in the absence of light or under low irradiance conditions. In addition, storing the plants in the dark at 35 °C for 48 h induced the abscission of 79.7% of the leaves but when 1-MCP was applied, this rate was reduced to 9.4%.…”

Exposure to ethylene is one of the main factors compromising the quality and shelf life in the post-production phase of potted ornamental plants and flowers in general. In preliminary tests to determine the desirable characteristics of a potted ornamental pepper (Capsicum annuum L.), the accession BGH 1039, from the Vegetable Germplasm Bank of the Federal University of Viçosa, was highlighted. However, this accession was sensitive to ethylene. Thus, this study aims to evaluate the influence of 1-methylcyclopropene (1-MCP) in extending the longevity of potted ornamental pepper. Potted peppers were placed in separate 60-L sealed chambers for the control, 1-MCP and ethylene treatments. To evaluate the quality and post-production shelf life, plants of all treatments were kept at 25 ± 1 °C under white fluorescent light with an intensity of 8-10 μmol s -1 m -2 and 60-65% relative humidity and watered whenever necessary. In plants treated with 10 μL L -1 of ethylene for 48 h, there was a reduction in the content of chlorophyll a and in total chlorophyll. Pre-treatment with 1 µL L -1 of 1-MCP followed by the application of 10 µL L -1 of ethylene for 48 h was effective in maintaining the green coloration of the leaves and in reducing leaf and fruit abscission over the 18 days of shelf life, demonstrating the efficiency of this product in blocking the action of ethylene. 1-MCP improved the quality and commercial durability of potted BGH 1039 ornamental pepper. Influência do 1-metilciclopropeno na longevidade de pimenta ornamental de vasoRESUMO: A exposição ao etileno é um dos principais fatores que comprometem a qualidade e tempo de prateleira na fase de pós-produção de plantas e flores ornamentais em geral. Em ensaios preliminares para determinação de características desejáveis para pimentas ornamentais em vaso, o acesso BGH 1039 (Capsicum annuum L.) do banco de Germoplasma de Hortaliças da Universidade Federal de Viçosa obteve destaque, no entanto, apresentou-se sensível ao etileno. Desta forma, este trabalho teve como objetivo avaliar a influência da utilização de 1-MCP em estender a longevidade de pimenta ornamental em vaso. Pimentas em vasos foram colocadas em câmaras seladas de 60 L para os tratamentos controle, 1-MCP e etileno. Para avaliação da qualidade e vida de prateleira pós-produção, plantas de todos os tratamentos foram mantidas a 25 ± 1 °C sob luz fluorescente branca com intensidade de 8-10 μmol s -1 m -2 , umidade relativa de 60-65% e regadas quando necessário. Nas plantas tratadas com 10 μL L -1 de etileno durante 48 h houve redução do conteúdo de clorofila a e clorofila total. O pré-tratamento com 1 µL L -1 de 1-MCP seguido de 10 µL L -1 de etileno por 48 h foi eficaz na manutenção da coloração verde das folhas e na redução da abscisão de folhas e frutos ao longo dos 18 dias de vida de prateleira, demonstrando a eficiência deste produto em bloquear a ação do etileno. O 1-MCP melhora a qualidade e a durabilidade comercial da pimenta ornamental BGH 1039 em vaso.Palavras-chave: Capsicum annuum L.; clorofila;...

1-MCP has been effectively used as an antagonist of ethylene deleterious actions in flowers and ornamental plants. The objective was to evaluate the efficiency of 1-MCP (0.0, 0.5, 1.0 and 1.5 g m-3) in maintaining post-production quality of exogenous ethylene sensitive ornamental pepper. Two commercial varieties were evaluated: Pimenta Colorida and Pimentão Ornamental, both Capsicum annuum. The pre-treatment with 1-MCP, regardless of the applied concentration, was effective in blocking the ethylene action reducing the leaves abscission, flowers and fruits of both genotypes by 100%. Plants pretreated with 1-MCP had postproduction life increased by eight and nine days for Pimenta Colorida and Pimentão Ornamental, respectively. The 1-MCP application at the concentration of 1.0 g m-3 is efficient in maintaining ornamental quality and prolonging the shelf life of Pimenta Colorida and Pimentão Ornamental.
