Resumo: | The production of coffee seedlings in the south and southeast regions of Brazil is constrained by eventual frosts. The protection of coffee seedlings, which are grown by the utilization of containers and plastic coverings, was evaluated in Londrina, State of Parana, during the winter of 2000. The utilized plastic coverings were composed of single and double layers of black and white polyethylene. The seedlings produced in both materials were also evaluated in cold chamber, in order to verify the vulnerability of root system. The temperatures of leaves and root system were monitored by thermocouples connected to a data logger. The results of this experiment showed that plastic coverings of double layers were efficient to protect the seedlings against low night temperature of leaves. The seedlings produced in containers showed lower temperatures in the roots, which suggests more susceptibility to frost damages. Therefore, a special caution must be taken with seedlings grown in containers during the winter, in order to avoid frost damages |

A proteção de mudas de café produzidas em tubetes e saquinhos plásticos com camadas simples e duplas de polietileno preto e branco trançado foi avaliada em Londrina, Estado do Paraná, durante o inverno de 2000. As mudas produzidas nos dois tipos de recipientes foram também avaliadas em câmara fria, com a finalidade de verificar a vulnerabilidade do sistema radicular. As temperaturas das folhas próximas ao sistema radicular foram monitoradas com pares termoelétricos conectados a um datalogger. Os resultados mostraram que camadas duplas de coberturas plásticas sobre as mudas são eficientes para reduzir a queda de temperatura noturna das folhas, podendo contribuir para proteção contra geadas. As mudas produzidas em tubetes apresentaram temperaturas menores nas raízes, indicando maior suscetibilidade a danos por geadas. Tais resultados indicam que se deve tomar cuidados extras de proteção de viveiros com mudas em tubetes para se evitar maiores prejuízos com geadasUniversidade Estadual de Maringá2008-04-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/179710.4025/actasciagron.v26i4.1797Acta Scientiarum.
