Resumo: | This work aimed to evaluate on use of physiological traits to identify genotypes of arabic coffee tolerant to Meloidogyne paranaensis when cropped in areas subjected to water deficits. The experiment was performed in field conditions with two genotypes: 16(MG 0179-1R1) and 28(0179-3 MGR1) and two cultivars: IPR-100 (resistant control) and Mundo Novo IAC379-19 (susceptible control) in a randomized block design with five replicates. The evaluated characteristics were: nematode population at the root, production, crown diameter, plant height, vegetative vigor, predawn leaf water potential (ψam), net photosynthesis (A), stomatal conductance (gs), transpiration (E), leaf temperature (TF), water use efficiency (WUE) and chlorophyll a fluorescence parameters. Genotypes 16, 28 and IPR100 showed higher vegetative growth and higher production than cv. Mundo Novo, especially the genotype 28. The leaf water potential was higher in genotypes16, 28 and IPR-100 compared to cv. Mundo Novo. However, the genotypes showed no differences in gas exchanges. According to the chlorophyll a fluorescence parameters, genotype 28 showed better photochemical performance and acclimation to water deficit. The physiological characteristics identify tolerant genotypes to Meloidogyne paranaensis when cropped in areas subjected to water deficits, especially for the analysis of chlorophyll fluorescence, since it can be used in large-scale assessments. |

O experimento foi instalado com dois genótipos de Coffea arabica L.: 16 (MG 0179-1 R1) e 28 (MG 0179-3 R1) e duas cultivares: IPR-100 (testemunha resistente) e Mundo Novo IAC 379-19 (testemunha suscetível), em delineamento de blocos casualizados com cinco repetições. Foram avaliados a população de M. paranaenses, produção, o diâmetro de copa, altura de planta, vigor vegetativo, potencial hídrico antemanhã (ψam), a fotossíntese líquida (A), a condutância estomática (gs), transpiração (E), temperatura foliar (TF) e eficiência do uso da água (EUA) e parâmetros de fluorescência da clorofila a. Os genótipos 16, 28 e IPR100 apresentaram maior desenvolvimento vegetativo e maior produção do que o genótipo Mundo Novo, com destaque para o genótipo 28. Verificou-se maior potencial hídrico nos genótipos 16, 28 e IPR-100 comparados à cv. Mundo Novo. Entretanto, os genótipos não apresentaram diferenças quanto às trocas gasosas. De acordo com os parâmetros de fluorescência da clorofila a, o genótipo 28 apresentou melhor desempenho fotoquímico e capacidade de aclimatação ao déficit hídrico. Pelas características fisiológicas identificam-se genótipos tolerantes ao Meloidogyne paranaensis, em áreas sujeitas ao déficit hídrico, com destaque para a análise de fluorescência da clorofila a que apresenta potencial para avaliações em larga escala.Editora UFLA2015-05-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/868Coffee Science - ISSN 1984-3909; Vol. 10 No. 2 (2015); 242 - 250Coffee Science; Vol. 10 Núm. 2 (2015); 242 - 250Coffee Science; v. 10 n. 2 (2015); 242 - 2501984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/868/pdf_178Copyright (c) 2015 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessSilva, Vânia AparecidaSalgado, Sônia Maria de LimaSá, Lígia Alcalde deReis, André MoraesSilveira, Helbert Rezende de OliveiraMendes, Antônio Nazareno GuimarãesBarbosa, João Paulo Rodrigues Alves DelfinoPereira, Antonio Alves2015-06-02T14:28:49Zoai:coffeescience.ufla.br:article/868Revistahttps://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:2024-05-21T19:53:51.717547Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
