e0“In constant light, whole apples (cv. Red Spy) that received alternating 6/25°C treatment accumulated more phenylalanine ammonia-lyase (PAL) and anthocyanin than those receiving constant 25° throughout the course of experiment”
e5“PAL activity was found to be negatively correlated with activity of PAL-IS”

Other claims from this paper (13)
- Intervention effect Whole apples under alternating 6/25°C accumulated more PAL than under constant 25° in constant light.
- Intervention effect Whole apples under alternating 6/25°C accumulated more anthocyanin than under constant 25° in constant light.
- Intervention effect Low temperature (6°) stimulated the activity of PAL in apples when applied in the dark period.
- Intervention effect Low temperature (6°) stimulated the synthesis of anthocyanin in apples when applied in the dark period.
- Intervention effect The activity of PAL-IS was lower in apples under alternating 6/25° than under constant 25° in constant light.
- Intervention effect In constant darkness, apples showed no accumulation of PAL and anthocyanin.
- Intervention effect The level of PAL-IS increased steadily in apples incubated in constant darkness.
- Intervention effect Nitrogen deficiency increased PAL accumulation in the leaves of greenhouse-grown apple trees.
- Intervention effect Nitrogen deficiency decreased PAL-IS accumulation in the leaves of greenhouse-grown apple trees.
- Intervention effect Potassium deficiency increased PAL accumulation in the leaves of greenhouse-grown apple trees.
- Intervention effect Potassium deficiency decreased PAL-IS accumulation in the leaves of greenhouse-grown apple trees.
- Mechanism Low temperature reduces PAL-IS level and increases PAL accumulation, which increases anthocyanin accumulation in apple skin.
- Mechanism Nitrogen and potassium deficiencies reduce PAL-IS level and increase PAL accumulation in apple leaves.
