Resumo: | The water content of seeds and temperature affect the biological processes, determining different results when seeds areexposed to different levels of these factors. When seeds are subjected to priming, we expect improvement in the physiological qualityof seeds, but while promising, this procedure is still in the experimental phase in coffee seeds. In order to evaluate the effects of solidmatrix priming at three different temperatures to evaluate the performance of coffee seeds (Coffea arabica L.) stored for up to twelvemonths, we carried out this research at the Central Laboratory of Seed Analysis in the Agriculture Department, Universidade Federalde Lavras, Lavras - MG. Seeds with 36.0% moisture content were sorted, processed, packed in polyethylene bags and kept in coldstorage for up to 12 months. At quarterly intervals, the seed samples were subjected to solid matrix priming, at temperatures of 20 °C,30 °C and 40 °C for 6 days. One control, without priming, was also evaluated. The physiological conditioning of solid matrix primingof C. Arabica seeds, held for 6 days at 20 °C and 30 °C favors the emergence of seedlings in seeds stored for 9 months and under 40°C, is harmful to the C. arabica seeds. |

Com objetivo de avaliar os efeitos do priming em matriz sólida em três diferentestemperaturas sobre o desempenho de sementes de café (Coffea arabica L.) armazenadas por até doze meses, realizou-se a presentepesquisa no Laboratório Central de Análise de Sementes do Departamento de Agricultura da Universidade Federal de Lavras, Lavras –MG. Sementes com 36,0% de umidade foram classificadas, tratadas, acondicionadas em embalagens de polietileno e armazenadas emcâmara fria por até 12 meses. Em intervalos trimestrais, as amostras de sementes foram submetidas ao priming em matriz sólida, emtemperaturas de 20 oC, 30 oC e 40 oC, por 6 dias. Uma testemunha, sem priming, foi também avaliada.
