Resumo: | Exposure to ethylene of ornamental plants is one of the factors that affect the life cycle post-production of these plants. The aim of this work was to evaluate the effects of paclobutrazol (PBZ) on the ethylene related responses of ten pepper cultivars of the genus Capsicum and one Solanum by simulating transport and commercialization. The cultivars were treated with PBZ at concentrations of 0, 5, 10 and 20 mg L-1 applied on the potted cultivation substrate. When the plants had 30% of ripe fruits, they were transferred to a 90 L sealed container and treated with 10 μL L-1 ethylene for 48 hours and then kept at room temperature. Percentages of leaf (LA) and fruit abscission (FA) the plants were recorded at every two days (48h, 96h and 144h). The design used was completely randomized, in an 11 x 4 factorial scheme. The PBZ did not completely inhibit the deleterious effects of exogenous ethylene on plants. However, the ‘Pérola Negra’ showed moderate sensitivity for leaf and fruit abscission, and the ‘Bode Vermelha’ for leaf abscission at a concentration of 10 mg L-1. PBZ prevented partially the abscission of fruits of the ‘Pirâmide Ornamental’ pepper at rates of 5 and 10 mg L-1, and ‘Tabasco’ pepper at a concentration of 10 mg L-1. In addition, cultivars showed darker foliage when treated with PBZ. |

El objetivo de este estudio fue evaluar los efectos del paclobutrazol (PBZ) sobre la sensibilidad al etileno de diez cultivares de pimiento del género Capsicum y un Solanum, en simulación de transporte o comercialización. Los cultivares de pimiento con PBZ a concentraciones de 0, 5, 10 y 20 mg L-1 sobre el sustrato de cultivo en maceta. Cuando las plantas tenían 30% de frutos maduros, se transfirieron a un recipiente sellado de 90 L y se trataron con etileno a 10 μL L-1 durante 48 horas, luego se mantuvieron a temperatura ambiente. Los porcentajes de abscisión de hojas (LA) y frutos (AF) de las plantas se registraron cada dos días (48, 96 y 144h) después del tratamiento con etileno. El diseño experimental fue completamente al azar, en un esquema factorial de 11 x 4. El PBZ no inhibió completamente los efectos deletéreos del etileno exógeno en las plantas. Sin embargo, la ‘Pérola Negra’ mostró una sensibilidad moderada para la abscisión de hojas y frutos y la ‘Bode vermelha’ para la abscisión de hojas a una concentración de 10 mg L-1. Moderadamente, PBZ impidió la abscisión de frutos de pimiento ‘Pirâmide ornamental’ a dosis de 5 y 10 mg L-1, y pimiento ‘Tabasco’ a una concentración de 10 mg L-1. Además, los cultivares mostraron un follaje más oscuro cuando se trataron con PBZ.A exposição ao etileno de plantas ornamentais é um dos fatores que afetam o ciclo de vida pós-produção destas plantas. O objetivo do estudo foi avaliar os efeitos do paclobutrazol (PBZ) sobre a sensibilidade ao etileno de dez cultivares de pimenta do genêro Capsicum e uma Solanum, em simulação de transporte ou comercialização. As cultivares foram tratadas com PBZ nas concentrações 0, 5, 10 e 20 mg L-1 sobre o substrato de cultivo em vaso. Quando as plantas apresentaram 30% dos frutos maduros, foram transferidas para um recipiente vedado de 90 L e tratados com etileno à 10 μL L-1 por 48 horas, em seguida, mantidas à temperatura ambiente. As porcentagens de folhas (LA) e abscisão de frutos (AF) das plantas foram registradas a cada dois dias (48, 96 e 144h). O delineamento utilizado foi inteiramente casualizado, em esquema fatorial 11 x 4. O PBZ não inibiu totalmente os efeitos deletérios do etileno exógeno nas plantas. Porém, a ‘Pérola Negra’ apresentou sensibilidade moderada para abscisão de folhas e frutos, e a ‘Bode vermelha’ para abscisão foliar na concentração 10 mg L-1. De forma moderada, o PBZ impediu a abscisão de frutos da ‘Pirâmide ornamental’ nas doses 5 e 10 mg L-1, e da pimenta ‘Tabasco’ na concentração 10 mg L-1. Além disso, os cultivares apresentaram folhagens mais escuras quando tratadas com PBZ.Research, Society and Development2022-01-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2526910.33448/rsd-v11i2.25269Research, Society and Development; Vol. 11 No. 2; e1911225269Research, Society and Development; Vol. 11 Núm. 2; e1911225269Research, Society and Development; v. 11 n. 2; e19112252692525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/25269/22254Copyright (c) 2022 Mayana Ferreira Nascimento; Fernanda Ferreira de Araújo; Rusthon Magno Cortez dos Santos; João José da Silva Neto; Claudio Horst Bruckner; Fernando Luiz Fingerhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNascimento, Mayana FerreiraAraújo, Fernanda Ferreira de Santos, Rusthon Magno Cortez dosSilva Neto, João José daBruckner, Claudio HorstFinger, Fernando Luiz 2022-02-07T01:42:50Zoai:ojs.pkp.sfu.ca:article/25269Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:43:35.544777Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
