Other claims from this paper (11)
- Observation In undamaged control fruits all three polyamine levels were higher in Fortune than in Clementine mandarins.
- Observation In undamaged control mandarin fruits, putrescine and spermine levels tended to diminish during the experiment.
- Observation In undamaged control Fortune mandarins, spermidine levels increased slightly during the experiment.
- Observation In undamaged control Clementine mandarins, spermidine levels showed a prominent peak 6 hours after storage.
- Intervention effect In general, polyamine levels in the peel of mandarins increased following bruising.
- Intervention effect The magnitude of the bruising-induced polyamine increase differed between the two cultivars and among the applied forces.
- Association Putrescine levels were positively correlated with the applied bruising force in Fortune mandarins.
- Intervention effect In Clementine mandarins only the 20 N force was effective on putrescine levels.
- Intervention effect Spermidine levels in Fortune mandarins also increased following injury.
- Intervention effect In Fortune mandarins there was no difference in the spermidine response among the three forces used.
- Intervention effect Spermine levels in bruised mandarins were slightly higher than control levels after 48 hours, but not higher than initial levels.
