Resumo: Abiotic stresses such as drought can significantly reduce the yield conilon coffee (Coffea canephora Pierre ex Froehner). The objective was to evaluate the influence of the fraction of available soil water on the initial development conilon coffee, evaluating with different water availability. The trial was carried out in the greenhouse of the Agricultural Science Center, Federal University of Espírito Santo, Alegre, ES, in a split-plot 4 x 5, and the plots with four levels of water deficit (100, 50, 30 and 10 % of available water in the soil), and the subplot with five assessment times (1, 30, 60, 90 and 120 days after onset of drought) in a completely randomized design with four replicates. The parameters evaluated were: matter of shoot dry, matter of the root system dry, plant height and leaf area. To evaluate the recovery of plants after drought, they are kept for 30 days with soil moisture close to field capacity. The best results of initial development conilon coffee were found when using the levels of 100 and 50% of available water in the soil there were no differences among them, however, differing from 30 to 10% of available water. Coffee subjected to longer periods of drought, significant losses in the initial development, undermining the recovery process after the plants deficit.

Assim, objetivou-se avaliar a influência da fração de água disponível no solo sobre o desenvolvimento inicial do cafeeiro conilon, trabalhando com diferentes disponibilidades hídricas. O experimento foi conduzido em casa de vegetação do Centro de Ciências Agrárias da Universidade Federal do Espírito Santo, em Alegre, ES, em esquema de parcelas subdivididas 4 x 5, havendo nas parcelas quatro níveis de déficit hídrico (100, 50, 30 e 10% da água disponível no solo), e nas subparcelas cinco épocas de avaliações (1º, 30º, 60º, 90º e 120º dia, após o  início do déficit hídrico), em um delineamento inteiramente casualizado, com quatro repetições. As variáveis avaliadas foram: matéria da parte aérea seca, matéria do sistema radicular seco, altura das plantas e área foliar. Objetivando-se avaliar a recuperação das plantas após déficit hídrico, as mesmas foram mantidas, por 30 dias, com umidade do solo próxima à capacidade de campo. Os melhores resultados de desenvolvimento inicial do cafeeiro conilon foram encontrados quando se utilizaram os níveis de 100 e 50% da água disponível no solo, não diferindo entre si, porém diferindo dos  níveis de 30 e 10% da água disponível. O cafeeiro submetido a maiores períodos de déficit hídrico apresentou perdas significativas no desenvolvimento inicial, comprometendo o processo de recuperação das plantas após déficit.Editora UFLA2015-02-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/733Coffee Science - ISSN 1984-3909; Vol. 10 No. 1 (2015); 46 - 55Coffee Science; Vol. 10 Núm. 1 (2015); 46 - 55Coffee Science; v. 10 n. 1 (2015); 46 - 551984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/733/pdf_158Copyright (c) 2015 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessRodrigues, Rogério RangelPizetta, Samuel Colados Reis, Edvaldo FialhoGarcia, Giovanni de Oliveira2015-06-02T03:32:20Zoai:coffeescience.ufla.br:article/733Revistahttps://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:2024-05-21T19:53:48.732404Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
