Temperature and maintenance solution effects on postharvest quality of Zingiber spectabile Griff.


Floral stems of gingiber (Zingiber spectabile Griff.) were harvested at the Embrapa Tropical Agroindustry Experimental Campus, located in Fortaleza, state of Ceará, in the first hours of the morning, when the inflorescences presented from 15 to 20 cm of length. After the harvest the floral stems were lead for the Laboratory of Physiology and Postharvest Technology to the experimental unit, being submitted to the cleaning process, immersed for 30 seconds in solution fungicide and later submerged in water for withdrawal of the excess of fungicide solution. Soon was proceeded the basal cut of the steams (standardizing to 40 cm) and watering for period of one hour. The floral steams had been conditional to the treatments of cold storage in 13ºC or 15ºC and UR 85% associated with storage in commercial maintenance solution Flower® (30mL of the product for 1L of water) or in water. Every two days the fresh mass percentage and visual appearance were evaluated by means of subjective note scale. The treatments did not show significant differences on visual appearance remaining with quality for 16º day the harvest. Relating to fresh mass percentage, it did not have interaction between the factors separately solutions and temperature, having presented significant effect, with the floral steam stored in temperature of 13ºC and the stored in commercial maintenance solution presented bigger averages of that stored 15ºC and water, respectively. Key words: Zingiber spectabile Griff., maintenance solution , temperature.
