Resumo: In obtaining smaller plants the use of plant regulators such as paclobutrazol (PBZ) are used, however, there are currently no reports on the development of ornamental pineapple  produced by plants treated with PBZ, whereby the objective of this work was to evaluate the influence of PBZ on plant development to obtain smaller ornamental pineapple plants. In this sense, an experiment was carried out with a randomized block design, in a factorial arrangement of 3x4 subdivided plots, with three types of plants (arial sucker and plant sucker treated with PBZ and arial sucker of plants not treated with PBZ), with four seasons, eight replicates and four plants per plot. In each season, the number of leaves, width and length of leaf D, height and diameter of the plant base were evaluated. The sucker-type  plants treated with PBZ showed the highest growth rate and the greatest influence of the PBZ hormone. Since the hormone has a residual effect that can be transmitted to organs of sexual reproduction according to its ubiquation in the matrix plant, affecting its initial development.

En este sentido, se realizó un experimento con un diseño de bloques aleatorizados, en un arreglo factorial de parcelas subdivididas de 3x4, con tres tipos de esqueje (intermedio y basal de plantas tratadas con PBZ y intermedio de plantas no tratadas con PBZ), cuatro épocas, con ocho repeticiones y cuatro plantas por parcela. En cada ápoca se evaluó el número de hojas, ancho y largo de hoja D, altura y diámetro de la base del esqueje. Los esquejes de tipo basal de plantas tratadas con PBZ mostraron la mayor tasa de crecimiento y sufrieron mayor influencia de PBZ. La hormona tiene un efecto residual que es transmitido a los órganos destinados a la reproducción sexual de acuerdo con su ubicación en la planta madre, afectando su desarrollo y desenvolvimiento inicial.Na obtenção de plantas com menor porte o uso de reguladores vegetais como o paclobutrazol (PBZ) é usado, entretanto, não há relatos na atualidade sobre o desenvolvimento de mudas de abacaxizeiro ornamental produzidas por plantas tratadas com PBZ, pelo qual o objetivo deste trabalho foi avaliar a influência do PBZ no desenvolvimento vegetal para obter mudas de abacaxizeiro ornamental de menor porte. Neste sentido foi conduzido um ensaio com delineamento experimental em blocos casualizados, em arranjo fatorial de parcelas subdivididas 3x4, com três tipos de mudas (filhote-rebentão e rebentão de plantas tratadas com PBZ e filhote-rebentão de plantas não tratadas com PBZ), em quatro épocas, com oito repetições e quatro plantas por parcela. Em cada época, foram avaliados o número de folhas, a largura e o comprimento da folha D, a altura e o diâmetro da base das mudas. As mudas do tipo rebentão de plantas tratadas com PBZ apresentaram a maior taxa de crescimento e maior influência do hormônio PBZ. Sendo que o hormônio apresenta efeito residual que pode ser transmitido para órgãos de reprodução sexual segundo sua ubiquação na planta matriz, afetando seu desenvolvimento inicial.   Research, Society and Development2020-09-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/847810.33448/rsd-v9i10.8478Research, Society and Development; Vol. 9 No. 10; e2349108478Research, Society and Development; Vol. 9 Núm. 10; e2349108478Research, Society and Development; v. 9 n. 10; e23491084782525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/8478/7558Copyright (c) 2020 Hayver Olaya Téllez; Guilherme Vieira do Bomfim; Ana Cristina Portugal Pinto de Carvalho; Benito Moreira de Azevedo; Carlos Hernan Galo Lozanohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessTéllez, Hayver OlayaBomfim, Guilherme Vieira doCarvalho, Ana Cristina Portugal Pinto de Azevedo, Benito Moreira deLozano, Carlos Hernan Galo2020-10-31T12:03:23Zoai:ojs.pkp.sfu.ca:article/8478Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:30:56.670379Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
