Resumo: | Paclobutrazol can mitigate the negative effects of water stress in many plant species, however, for coffee plants is necessary to expand the knowledge base on the subject. In this research it was aimed to evaluate the morphophysiology of young plants of Coffea Arabica cv. ‘Catuaí Vermelho IAC 144’ in response to different water regimes and paclobutrazol concentrations applied in the soil. The trial was carried out in a greenhouse at Vitória da Conquista, BA. The experimental design was a randomized block with factorial arrangement represented by five concentrations of paclobutrazol (0, 50, 100, 150 and 200 mg L-1) applied in the soil and two water regimes (with and without water restriction) in five replicates.At 120 days after the application of plant growth regulator was evaluated the water status, the SPAD index and the morphological characteristics of plants. The application of paclobutrazol reduced the SPAD index and individual leaf area, and favored the water status of coffee plants under water restriction. The young coffee plants without water restriction and treated with the plant growth regulator, had higher leaf retention and SPAD index, and lowest individual leaf area. Paclobutrazol at high concentrations resulted in plants more compact. The water restriction provided less total leaf area, number of branches and dry weight of the coffee. |

Neste estudo, objetivou-se avaliar a morfofisiologia de plantas jovens de Coffea arabica var. ‘Catuaí Vermelho IAC 144’ em resposta a diferentes regimes hídricos e concentrações de paclobutrazol aplicado via solo. O experimento foi conduzido em casa de vegetação em Vitória da Conquista, BA. O delineamento experimental foi em blocos casualizados, com esquema fatorial representado por cinco concentrações de paclobutrazol (0, 50, 100, 150 e 200 mg L-1) aplicado via solo e dois regimes hídricos (com e sem restrição hídrica), em cinco repetições. Aos 120 dias após a aplicação do regulador vegetal avaliou-se o status hídrico, o índice SPAD e as características morfológicas das plantas. A aplicação de paclobutrazol reduziu o índice SPAD e a área foliar individual, e favoreceu o status hídrico dos cafeeiros sob restrição hídrica. As plantas jovens de café, sem restrição hídrica e tratadas com o regulador vegetal, tiveram maior retenção foliar e índice SPAD, e menor área foliar individual. A aplicação de paclobutrazol em concentrações elevadas resultou em plantas mais compactas. A restrição hídrica proporcionou menor área foliar total, número de ramos e massa seca dos cafeeiros.Editora UFLA2017-11-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/vnd.openxmlformats-officedocument.wordprocessingml.documenthttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1361Coffee Science - ISSN 1984-3909; Vol. 12 No. 4 (2017); 534 - 543Coffee Science; Vol. 12 Núm. 4 (2017); 534 - 543Coffee Science; v. 12 n. 4 (2017); 534 - 5431984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1361/pdf_1361https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1361/1814Copyright (c) 2017 Coffee Scienceinfo:eu-repo/semantics/openAccessRibeiro, André Felipe FialhoMatsumoto, Sylvana NaomiRamos, Paula Acácia SilvaSantos, Jefferson Luan Dias dosTeixeira, Ednilson Carvalhod’Arêde, Lucialdo OliveiraViana, Anselmo Eloy Silveira2017-11-28T15:57:51Zoai:coffeescience.ufla.br:article/1361Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:54:03.383792Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
