Resumo: Vegetative propagation or cloning of F1 hybrids represents an economy of time and resources for Coffea arabica L. breeding programs. Nevertheless, not much is known about the rooting system of coffee plants propagated by cuttings. An essay was carried out aiming to evaluate Coffea arabica rooting system of plants obtained by vegetative and seedling propagation. Cuttins of the Acaiá and Rubi cultivar with previously developed roots, about 3cm long, that have been free for 90 days of any contact with plant growth regulators were transplanted to plastic bags. At the same time, seeds from the same cultivars were planted on the same plastic bags and stored on a covered commercial nursery with 50% shading. Common cultivation methods were used during seedling development. Bioplant was used as substratum and Osmocote as fertilizer supplier. Root length and diameter were evaluated by using the computational program QUANTRAIZ. It was observed that young coffee plants originated by cuttings produced fine root system longer and heavier than the root system of plants formed by seeds. Most part of the roots developed by the seedlings, more than 98%, was composed by fine roots by which the plant is able to absorb water and mineral salts.

Entretanto, pouco se sabe sobre o sistema radicular de plantas de café propagadas vegetativamente. Objetivando avaliar o sistema radicular de mudas de C. arabica, obtidas por meio de estaquia e por semeadura, foi conduzido um experimento no qual estacas previamente enraizadas, após 90 dias sem o uso de regulador de crescimento, com raízes entorno de 3 cm, das cultivares Acaiá e Rubi, foram transplantadas para sacolas plásticas. Na mesma ocasião foi feita a semeadura das duas cultivares no mesmo tipo de sacola e colocadas em viveiro do tipo comercial, de cobertura, com sombreamento de aproximadamente 50%. Durante o desenvolvimento das mudas foram feitos os tratos culturais conforme o sistema convencional de produção de mudas. Como substrato foi utilizado o Bioplant® e como suprimento foi utilizado o fertilizante Osmocote. As mudas atingiram o padrão de muda de ano. As medições dos comprimentos e diâmetros das raízes foram feitas utilizando-se o programa computacional QUANTRAÍZ. Observou-se que mudas obtidas por meio de estacas possuem maior comprimento total das raízes e maior peso da matéria seca que mudas formadas por sementes. A maior parte do sistema radicular de todas as mudas, mais de 98%, constituiu de raízes finas por meio das quais as plantas absorvem água e os sais minerais.Editora UFLA2007-12-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/13Coffee Science - ISSN 1984-3909; Vol. 1 No. 1 (2006); p. 14-20Coffee Science; Vol. 1 Núm. 1 (2006); p. 14-20Coffee Science; v. 1 n. 1 (2006); p. 14-201984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporengspahttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/13/9https://coffeescience.ufla.br/index.php/Coffeescience/article/view/13/67https://coffeescience.ufla.br/index.php/Coffeescience/article/view/13/68Copyright (c) 2007 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessJesus, Adriana Madeira SantosCarvalho, Samuel Pereira deSoares, Ângela Maria2013-02-23T12:10:24Zoai:coffeescience.ufla.br:article/13Revistahttps://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:2024-05-21T19:53:25.585634Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
