Resumo
This work was based to study the influence of the storage temperature (cold and room temperature) in the quality of inflorescences strelitzia. The scapes were selected, labeled and there were zero problems concerning mechanical damage, disease and/or plagues. Subsequently this period, the scapes were moved randomly to recipients with water, in which two postharvest trials were conducted. In experiment 1, the flower scapes were placed in buckets with water from public supply and sanitation department and taken to a cold room at temperature of 7.5 ºC and RH of 90%, for a twelve day period. For the experiment 2, were kept under the same conditions but at room temperature for a period of six days. In both experiments, the visual analysis: color, gloss, stains (by assigning notes), opening and drop florets (count) were evaluated at intervals of four days in cold and every 48 hours at ambient temperature conditions. In both experiments, the visual analysis: color, gloss, stains (by assigning notes), opening and drop florets (count) were evaluated at intervals of four days in cold and every 48 hours at ambient temperature conditions. The sepal is the organ that showed greater loss in coloration. The variable gloss showed the same pattern for the two experiments. Incidences of stains on the inflorescences occurred in patches at room temperature. The scapes increased number of florets open in cold. This tendency did not occur at room temperature. No were observed differences in the fall of florets. Conclude that the storage temperature does not contribute to postharvest quality of strelitzia.
