Resumo: | Synthetic hormonal plant growth promoter (HPGP) has been used in agriculture, especially kinetin (KIN, cytokinin), gibberellic acid (GA3, gibberellin), and indolbutyric acid (IBA, auxin). The objective of this work was to evaluate rates and methods of application of a HPGP product (0.09 g L-1 of KIN; 0.05 g L-1 of GA3; 0.05 g L-1 of IBA) and its effects on wheat seedling growth. Two independent experiments were carried out in a greenhouse. The first was performed on Germitest® paper and the second in soil. In both cases, it was used a completely randomized design. The first trial, with 10 replicates, was carried out in a 2 × 2 × 4 factorial arrangement, being two wheat genotypes, two HPGP rates applied on the seeds, and four periods of seedling growth, totaling 160 experimental units. The second trial had four replicates, with treatments disposed in a 2 × 2 × 2 factorial arrangement, being two wheat genotypes, two HPGP rates applied on the seeds, and two HPGP rates applied on the leaves, totaling 32 experimental units. It was evaluated the growth of roots (number of roots/seedling and total root length/seedling) and the growth of leaves (length, width, and area). The application of HPGP on the seeds delayed the initial root growth and the leaf area expansion. However, this inhibitory effect was reversed along with the advance of seedling age. The combined application of HPGP on the seeds and on the leaves caused an antagonistic effect, with systematic growth reduction of wheat seedling roots. |

El objetivo de este trabajo fue evaluar dosis y métodos de aplicación de un producto conteniendo PHCP (0.09 g L-1 de KIN; 0.05 g L-1 de GA3; 0.05 g L-1 de IBA) y sus efectos sobre el crecimiento de plántulas de trigo. Se llevaron a cabo dos experimentos independientes en un invernadero. El primero se desarrolló en papel Germitest® y el segundo en suelo. En ambos casos se utilizaron diseños completamente aleatorizados. El primer ensayo, con 10 repeticiones, se realizó en un arreglo factorial 2 × 2 × 4, con dos genotipos de trigo, dos dosis de PHCP aplicadas a las semillas y cuatro períodos de crecimiento de las plántulas, totalizando 160 unidades experimentales. El segundo ensayo contó con cuatro repeticiones, con tratamientos dispuestos en un arreglo factorial 2 × 2 × 2, con dos genotipos de trigo, dos dosis de PHCP aplicadas a las semillas y dos dosis de PHCP aplicadas en las hojas, totalizando 32 unidades experimentales. Se evaluó el crecimiento de raíces (número de raíces/plántula y longitud total/plántula) y el crecimiento de hojas (largo, ancho, y área). La aplicación de PHCP en las semillas retrasó el crecimiento inicial de las raíces y la expansión del área foliar. Sin embargo, este efecto inhibidor se revirtió con la edad de las plántulas. La aplicación combinada de PHCP en las semillas y en las hojas provocó un efecto antagónico, con una reducción sistemática del crecimiento de las raíces de las plántulas de trigo.Promotores hormonais de crescimento de plantas (PHCP) têm sido utilizados na agricultura, especialmente cinetina (KIN, citocinina), ácido giberélico (GA3, giberelina), e ácido indolbutírico (IBA, auxina). O objetivo deste trabalho foi avaliar doses e métodos de aplicação de um produto contendo PHCP (0,09 g L-1 de KIN; 0,05 g L-1 de GA3; 0,05 g L-1 de IBA) e os seus efeitos no crescimento de plântulas de trigo. Dois experimentos independentes foram conduzidos em casa de vegetação. O primeiro foi desenvolvido em papel Germitest® e o segundo em solo. Em ambos os casos, foram utilizados delineamentos inteiramente casualizados. O primeiro ensaio, com 10 repetições, foi conduzido em arranjo fatorial 2 × 2 × 4, sendo dois genótipos de trigo, duas doses de PHCP aplicadas nas sementes, e quatro períodos de crescimento das plântulas, totalizando 160 unidades experimentais. O segundo ensaio continha quatro repetições, com tratamentos dispostos no arranjo fatorial 2 × 2 × 2, sendo dois genótipos de trigo, duas doses de PHCP aplicadas nas sementes, e duas doses de PHCP aplicadas nas folhas, totalizando 32 unidades experimentais. Foram avaliados os crescimentos radicular (número de raízes/plântula e comprimento total/plântula) e foliar (comprimento, largura e área). A aplicação do PHCP nas sementes atrasou o crescimento inicial das raízes e a expansão da área foliar. Porém, este efeito inibitório foi revertido com o avanço da idade das plântulas. A aplicação combinada de PHCP nas sementes e nas folhas ocasionou um efeito antagônico, com sistemática redução do crescimento de raízes das plântulas trigo.Research, Society and Development2020-11-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/997510.33448/rsd-v9i11.9975Research, Society and Development; Vol. 9 No. 11; e4769119975Research, Society and Development; Vol. 9 Núm. 11; e4769119975Research, Society and Development; v. 9 n. 11; e47691199752525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/9975/9010Copyright (c) 2020 Sérgio Ricardo Silva; Gabriel Zanardo Martinshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Sérgio RicardoMartins, Gabriel Zanardo2020-12-10T23:37:57Zoai:ojs.pkp.sfu.ca:article/9975Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:32:08.603718Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
