Longevity of torch ginger inflorescences with 1-methylcyclopropene and preservative solutions - doi: 10.4025/actasciagron.v33i4.11084

Resumo

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.
