The quality of Yukbo strawberry (Fragaria ananassa Duch.) fruit declines rapidly after harvest. Therefore, we examined the effects of nitric oxide (NO) on its respiration rate, quality, and shelf life. Strawberries were fumigated for 5 hr at 0, 50, 100, 200, or 500 μL/L NO atmospheres, followed by a hold at 18℃ in air. Treatment with NO delayed the onset of ethylene production and reduced respiration, which at 18℃ resulted in a maintained quality and prolonged shelf life. The NO treated strawberries were also firmer and had a lower incidence of disease than the untreated fruit.
