Other claims from this paper (8)
- Association Field anthocyanin increase before harvest coincided with falling temperature.
- Association Field anthocyanin increase before harvest coincided with increasing fruit ethylene production.
- Observation Under continuous white light, unripe detached apples had an anthocyanin accumulation optimum at 12 °C.
- Observation Under continuous white light, ripe detached apples had an anthocyanin accumulation optimum at 16–24 °C.
- Association PAL levels were higher at low than high temperatures.
- Observation PAL levels were higher in ripe than unripe apples.
- Intervention effect Intermittent light yielded lower PAL levels than continuous light.
- Intervention effect Intermittent light yielded lower anthocyanin levels, particularly in unripe apples.
