Other claims from this paper (11)
- Observation Photosynthetic efficiency gradually declined with maturation and ageing in unchilled plants.
- Association Maximum rubisco activity and CO2-saturated photosynthesis correlated near 1:1 except in senescing leaves.
- Observation Chlorophyll content declined strongly only late in senescence of the oldest leaves.
- Observation Photochemical fluorescence quenching declined strongly only late in senescence of the oldest leaves.
- Intervention effect Non-photoinhibitory chilling produced a similar ageing pattern.
- Intervention effect Chilled plants had lower total photosynthetic capacity than unchilled plants of the same size.
- Intervention effect Mildly photoinhibitory chilling strongly depressed rubisco activity in all leaves.
- Intervention effect Mildly photoinhibitory chilling strongly depressed photosynthetic capacity in all leaves.
- Observation Depression was partly reversible in young leaves.
- Mechanism Reduced CO2 fixation capacity increased susceptibility to photoinhibition at 20°C.
- Mechanism The authors attribute decreased photosynthetic capacity and growth after chilling to leaf ageing and senescence during chilling.
