Resumo: | The necessity of controlling the vegetative growth of fruit trees is a growing concern for farmers since vigorous plants tend to have lower fruit yields. The use of chemicals that inhibit the vegetative growth of plants, such as prohexadione-calcium (PCa), an inhibitor of gibberellins which is currently used as a growth regulator for apple trees, is an agricultural practice aimed to help in reducing pruning time and cost. Pear trees grafted on vigorous rootstocks tend to present high rates of vegetative growth, hindering fruit production. Thus, this work aimed to evaluate the effect of the application of different doses of the plant growth regulator PCa on the vegetative growth, pruning time, radiation incidence, and productive and quality parameters of ‘Packham’s Triumph’ and ‘Hosui’ pears grafted on vigorous rootstocks. Two PCa applications were carried out, the first after the falling of petals (2009-10-10), and the second twenty-one days after the first (2009-11-02). The observed results showed a significant effect of PCa in reducing the vegetative growth of the pear trees and the pruning time in both cultivars. The effect on photosynthetic active radiation (PAR) was observed only in the ‘Packham’s Triumph’ variety, not being observed for the ‘Hosui’ pear trees. No statistical difference was observed relative to the quality parameters and yield of the fruits, in both cultivars, showing that PCa application has not caused any deleterious effect on fruit development. |

El uso de productos químicos que inhiben el crecimiento vegetativo de las plantas, como la prohexadiona-calcio (CaP), un inhibidor de las giberelinas que se utiliza actualmente como regulador del crecimiento de los manzanos, es una práctica agrícola destinada a ayudar a reducir el tiempo y el coste de la poda. Los perales injertados sobre portainjertos vigorosos tienden a presentar altas tasas de crecimiento vegetativo, lo que dificulta la producción de frutos. Así, este trabajo tuvo como objetivo evaluar el efecto de la aplicación de diferentes dosis del regulador del crecimiento vegetal CaP sobre el crecimiento vegetativo, tiempo de poda, incidencia de radiación y parámetros productivos y de calidad de peras 'Packham's Triumph' y 'Hosui' injertadas en vigorosos portainjertos. Se realizaron dos aplicaciones de CaP, la primera después de la caída de pétalos (2009-10-10), y la segunda veintiún días después de la primera (2009-11-02). Los resultados observados mostraron un efecto significativo del CaP en la reducción del crecimiento vegetativo de los perales y el tiempo de poda en ambos cultivares. El efecto sobre la radiación fotosintética activa (RFA) se observó solo en la variedad "Packham's Triumph", no observándose en los perales "Hosui". No se observó diferencia estadística relativa a los parámetros de calidad y rendimiento de los frutos, en ambos cultivares, lo que demuestra que la aplicación de CaP no ha provocado ningún efecto deletéreo en el desarrollo del fruto.A necessidade de controlar o crescimento vegetativo das árvores frutíferas é uma preocupação crescente para os agricultores, uma vez que plantas vigorosas tendem a ter menor produção de frutos. O uso de produtos químicos que inibem o crescimento vegetativo das plantas, como a prohexadiona-cálcio (PCa), um inibidor das giberelinas que atualmente é utilizado como regulador do crescimento de macieiras, é uma prática agrícola que visa auxiliar na redução do tempo e custo da poda. As pereiras enxertadas em porta-enxertos vigorosos tendem a apresentar altas taxas de crescimento vegetativo, dificultando a produção de frutos. Assim, este trabalho teve como objetivo avaliar o efeito da aplicação de diferentes doses do regulador de crescimento vegetal PCa sobre o crescimento vegetativo, tempo de poda, incidência de radiação e parâmetros produtivos e de qualidade de pêras 'Packham's Triumph' e 'Hosui' enxertadas em porta-enxertos vigorosos. Foram realizadas duas aplicações de PCa, a primeira após a queda das flores (2009-10-10) e a segunda 21 dias após a primeira (2009-11-02). Os resultados observados mostraram efeito significativo do PCa na redução do crescimento vegetativo das pereiras e do tempo de poda em ambas as cultivares. O efeito na radiação fotossinteticamente ativa (RFA) foi observado apenas na variedade ‘Packham’s Triumph’, não sendo observado para as pereiras ‘Hosui’. Não foi observada diferença estatística em relação aos parâmetros de qualidade e produtividade dos frutos, em ambas as cultivares, mostrando que a aplicação de PCa não causou nenhum efeito deletério no desenvolvimento dos frutos.Research, Society and Development2021-07-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1680110.33448/rsd-v10i8.16801Research, Society and Development; Vol. 10 No. 8; e3110816801Research, Society and Development; Vol. 10 Núm. 8; e3110816801Research, Society and Development; v. 10 n. 8; e31108168012525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/16801/15177Copyright (c) 2021 Odair Ângelo Dalzochio; Wendel Paulo Silvestre; Gabriel Fernandes Paulettihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDalzochio, Odair ÂngeloSilvestre, Wendel PauloPauletti, Gabriel Fernandes2021-08-21T18:46:59Zoai:ojs.pkp.sfu.ca:article/16801Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:37:15.554735Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
