Resumo: Coffee micropropagation allows the multiplication of hybrids and segregating genotypes, and reduces from 30 to nearly 10 years, the time required to obtain new coffee cultivars. However, this technique is not yet ready for Coffea arabica L. large scale propagation and the field performance of plants produced through this process is not well known. This work aimed to study the behavior of plants propagated by indirect somatic embryogenesis. Two assays were carried out to compare vegetative propagated plants with seed derived plants. The first one studied radicular system morphology and plant response to water restrain and water excess. The second one was conducted in field conditions to evaluate the post-planting vegetative growth. In the greenhouse assay the vegetative propagated plants had higher vegetative growth than seed propagated plants in the following parameters: leaf and stem dry weight, plant height and number of orthotropic branches. There was no difference between the two propagation methods for the response to water stress. In the field trial the vegetative propagated plants showed higher vegetative growth during the first seven months for all the parameters evaluated. It was concluded that somatic embryogenesis propagated plants have better vegetative growth during the first seven months in the field and a similar response to plants obtained from seeds in water deficiency and water excess conditions.

Ela permite a multiplicação de híbridos e de genótipos segregantes, de alto valor agronômico, e possibilita reduzir, consideravelmente, o tempo necessário para o lançamento de novas cultivares. Todavia, existem poucos estudos sobre o comportamento de plantas obtidas por ES sob condições de baixa disponibilidade de água no solo. Neste contexto, objetivou-se avaliar o efeito de diferentes níveis de água disponível no solo em cafeeiros propagados via embriogênese somática, em comparação com cafeeiros propagados por sementes. Instalou-se um ensaio, em casa de vegetação, em esquema fatorial 4x2, sendo quatro níveis de água disponível no solo (40%, 70%, 100% e 130% da capacidade de campo) e dois métodos de propagação (embriogênese somática e semente), utilizando-se mudas de seis meses de idade da cultivar Catuaí Vermelho IAC 44. Foram avaliados a massa seca das folhas, do caule e das raízes, a área foliar, a altura, o diâmetro do caule, o comprimento radicular, o número de ramos plagiotrópicos e o número de nós do ramo ortotrópico. Concluiu-se que plantas propagadas por embriogênese somática apresentam desenvolvimento semelhante ao de plantas obtidas por sementes em diferentes condições de disponibilidade de água no solo, e que o sistema radicular de cafeeiros propagados via embriogênese somática não limita, e pode até colaborar, para um maior desenvolvimento das plantas na fase inicial da cultura.Editora UFLA2011-09-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/163Coffee Science - ISSN 1984-3909; Vol. 6 No. 2 (2011); 114-119Coffee Science; Vol. 6 Núm. 2 (2011); 114-119Coffee Science; v. 6 n. 2 (2011); 114-1191984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/163/pdfCopyright (c) 2012 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessReis Almeida, Gustavo RennóHenrique Siqueira de Carvalho, CarlosJosé Guimarães, Rubens2013-02-24T12:42:32Zoai:coffeescience.ufla.br:article/163Revistahttps://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:2024-05-21T19:53:32.105559Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
