ABSTRACT :
Respiration rate and superoxide dismutase (SOD) activity in both peel and flesh increased during storage of ponkan (C. reticulata) fruits which had been subjected to compression bruising; increases were larger following compression at 6.0 kg, compared with compression at 4.5 kg. Respiration rate and SOD activity decreased rapidly at 40 and 65 days after bruising, respectively, to reach levels similar to those of the control fruits. Peel conductivity increased with the degree of bruising, indicating increased membrane permeability. It is suggested that compression bruising reduces nutritive value and eating quality by stimulating fruit senescence.
