A completely factorial randomized 2 x 5 design, with three replications. Weight loss (%), total soluble solids (TSS), titratable acidity (TA), respiration rate (TR) and ethylene production (PE) were analyzed. Also a sensory evaluation using the five-point hedonic scale was conducted, evaluating the attributes of taste, palatable texture, visual appearance and rotting. The results indicated that at lower temperature, the physical, chemical and sensory characteristics of the ray florets of dahlia, were kept for 14 days, compared to those kept at 22 ° C, where the quality of florets was lost after the day 3 of storage. At 4 ° C the yellow variety presented the lowest weight loss, TSS, TR and PE. The yellow and white varieties showed the heighest values of brightness, chroma and hue angle. Finally, in the sensory evaluation, the red, cherry and white varieties showed good texture and good flavor, in all the varieties there were no signs of rot during the storage period.
