e6“the de-epoxidation of xanthophyll cycle pigments' pool on basis of Chl was higher in the abaxial side”
e4“Both the slower decrease in the photochemical quenching and the higher non-photochemical quenching may account for the higher resistance to chilling stress in the adaxial side of Rumex K-1 leaves”

Other claims from this paper (8)
- Intervention effect Under chilling, the maximum quantum yield of PS2 in the abaxial leaf side decreased more markedly than in the adaxial side.
- Intervention effect Under chilling stress, actual photochemical efficiency of PS2, photosynthesis and photorespiration declined more significantly in the abaxial side than in the adaxial side.
- Observation Before chilling, the two leaf sides of Rumex K-1 showed no obvious difference in actual photochemical efficiency of PS2, photosynthesis and photorespiration.
- Intervention effect Chlorophyll and carotenoid contents of Rumex K-1 were not affected by chilling.
- Observation Chlorophyll and carotenoid contents of Rumex K-1 were higher in the adaxial side.
- Observation Non-photochemical quenching was higher in the adaxial side of Rumex K-1 leaves.
- Mechanism Slower decrease in photochemical quenching and higher non-photochemical quenching may account for the higher chilling resistance of the adaxial side.
- Mechanism The decline in photochemical efficiency of PS2 in the abaxial side was partly attributed to lower carboxylation efficiency there.
