Abstract

Effects of varying gamma-irradiation doses and polyethylene package on the quality and chemical components of Jonathan apples were investigated. The results obtained are as follows: 1. The doses of 50 to 100 krad were effective in the control of fruit rot and physiological disorders. 2. Gamma-irradiation to Jonathan apples rather accelerated shrivelling at the early stage of storage period. 3. Combined treatments of radiation and polyethylene package enabled to control the shrivelling of apples. 4. The rate of freight loss was lower in the irradiated and/or packing lots than control 5. Gamma-irradiation and polyethylene package did not appear to influence on the sugar content of apples.
