Other claims from this paper (12)

Intervention effect At 11 °C, apparent photosynthesis exceeded that at 23 °C for up to 17 days.
Intervention effect At 3 °C apparent photosynthesis was little affected for the first three days.
Intervention effect At 3 °C apparent photosynthesis declined to about 70% of pretreatment by day 10.
Intervention effect Accounting for dark respiration at 3 °C, actual photosynthesis declined to about 50% by day 10.
Observation Photosynthesis then declined slowly over time.
Observation Rapid recovery after transfer back to 23 °C occurred only after at most one day at low temperature.
Observation After 17 days at 11 °C, apparent photosynthesis returned to pretreatment rates by day 7.
Observation After at least four days at 3 °C, apparent photosynthesis recovery reached 80% by day 7.
Observation After at least four days at 3 °C, apparent photosynthesis recovery reached 90% by day 23.
Observation Dark respiration initially increased after transfer from 3 to 23 °C.
Association Dark respiration later decreased at 23 °C as apparent photosynthesis increased.
Mechanism The authors attribute initial chilling injury to respiratory rather than photosynthetic apparatus.

Other claims from this paper (5)

Intervention effect Saturating ADP with arsenate decreased steady-state H+ uptake in illuminated chloroplasts.
Intervention effect ATP or ADP without arsenate enhanced the light-induced chloroplast H+ gradient by 0.15 to 0.2 unit.
Intervention effect ADP with arsenate decreased ΔpH by up to 0.4 unit.
Intervention effect Phlorizin prevented the ADP-associated ΔpH decrease.
