Reduction of wound-induced respiration and ethylene production in carrot root tissues by gamma irradiation.

The effects of irradiation with gamma rays on wound-induced respiration and ethylene production were investigated in grated carrot (cv. Nandor) root tissues allowed to age in air for 4 days at 20 deg C. Two days after treatment, gamma rays (2 kGy) had reduced respiration by 50% and ethylene production by 80%. The respiratory quotient, close to 1.0, was not affected by the treatment. The lowering of induced-respiration by irradiation in grated tissues resulted in a sugar consumption that was half that in non-treated tissues. Confirmation of these results was obtained with grated carrots stored in plastic bags. After 7 days of storage in bags at 10 deg , the atmospheres over irradiated grated carrots had lower and higher percentages of CO2 and O2, respectively, than the controls. Beside its effects on the reduction of microbial spoilage, gamma radiation was shown to induce physiological modifications in wounded plant tissues, delaying senescence, which is of potential interest for the maintenance of shelf-life of minimally processed vegetables.
