Effect of Gamma Radiation on Rate of Ethylene and Carbon Dioxide Evolution by Lemon Fruit

Abstract

Gamma radiation induced sufficient production of ethylene gas by lemon fruits (Citrus limon) to cause degreening of the fruit. The rate of respiration of irradiated lemon fruit increased immediately after treatment. After a few days the increase was followed by a decline, giving a curve resembling the autogenous climacteric common to many fruits, but atypical for citrus. The production of ethylene followed the same general pattern as the respiration rate, but reached a peak 1-2 days later.
