Postharvest quality of “Yukbo” strawberry (Fragaria ananassa Duch.) maintained by nitric oxide (NO)
The potential of NO to influence postharvest quality of “Yukbo” Strawberry (Fragaria ananassa Duch.) fruit was evaluated. “Yukbo” Strawberry were exposed to 0, 50, 100, 200 and 500 µL.L-1 NO at 15°C in air, the stored at 18°C. Strawberry quality rapidly after storage. Treatment with 200 µL.L-1 NO reduced respiration rate and ethylene production. There physiological responses affected fruit quality including firmness, weight loss. And senescent decay. Treated fruit were firmer and had weight loss and senescent decay than controls. Application of 200 µL.L-1 NO protected the calyx tissue during storage but fruit treated 500 µL.L-1 NO shoeing significant browning around the calyx. At this higher NO concentration extension in postharvest life was not as great as at lower NO concentration.
