Abstract
When comparing core and flesh tissue from post-climacteric apple (Malus domestica Linn.) fruit, it was found that core tissue manifested considerably higher activities of lipoxygenase, and superoxide dismutase and less endogenous anti-oxidant activity, while ethylene evolution in both types of tissue was approximately equal. Tree sprays of Ca(NO3)2 more than halved core ethylene evolution while having no effect on flesh ethylene or on lipoxygenase in either flesh or core. Results are interpreted in the light of a hypothesis that the more intensive core oxidative metabolism may play a key role in senescence of the whole fruit.
