This work aimed at the assessment of the influence of 1-MCP on ethrel action and on its association with preservative solutions on torch ginger. In the first experiment, the inflorescences were pre-treated with 1-MCP in sealed chambers at concentrations of 0, 1, 1.5, and 2.0 g m-3, for 24 hours. Later, the inflorescences were submitted to the treatment with ethrel (100 µL L-1) in sealed chamber for 24 hours. In the second experiment, the inflorescences were pre-treated with 1.5 g m-3 of 1-MCP for 24 hours, being posteriorly transferred to vases containing water, Flower®, Florissant®, and water without 1-MCP pre-treatment. The fresh matter and the quality of the inflorescence were daily appraised using the scale grading. The best results were obtained for 1.5 g m-3 of 1-MCP. The association between 1-MCP and Florissant® provided larger longevity and quality in the postharvest conservation, increasing in five days the longevity in relation to those kept only in water. O objetivo deste trabalho foi avaliar a influência do 1-MCP na ação do ethrel e associado a soluções conservantes em bastão do imperador. No primeiro experimento, as inflorescências foram pré- tratadas com 1-MCP em câmaras herméticas nas concentrações 0; 1; 1,5 e 2,0 g m-3 por 24h. Posteriormente foram submetidas ao tratamento com ethrel (100 µL L-1) em câmaras herméticas pelo mesmo período. No segundo experimento as inflorescências foram pré- tratadas em 1,5 g m-3 de 1-MCP por 24h e posteriormente transferidas para as soluções: água; Flower®, Florissant® e água sem pré-tratamento com 1-MCP. Diariamente foram avaliadas a massa fresca e a qualidade das inflorescências utilizando-se escala de notas. Os melhores resultados foram obtidos com 1,5 g m-3 de 1-MCP, que, associado ao Florissant® proporcionou maior longevidade e qualidade na conservação pós- colheita prolongando a vida de vaso em 5 dias em relação às mantidas somente em água
