Irradiation as a postharvest quarantine treatment for a new pluot cultivar

► “Flavor Fall” plums are prone to shrivel and irradiation worsened this problem. ► Fruit in the insect-proof bag that was treated with 900 Gy had very high levels of gel breakdown. ► Research into different forms of packaging might relieve the shrivel and gel breakdown problems. ► All other fruit quality parameters evaluated were not detrimentally affected by irradiation.
