- Intervention effect Chilling tomato leaves for 16 hours at 1 C decreased photosynthesis and transpiration.
- Mechanism Impaired chloroplast function accounted for about 35% of the photosynthesis inhibition.
- Mechanism Reduced stomatal conductance accounted for about 25% of photosynthesis inhibition.
- Intervention effect Chilling did not change the photosynthetic apparatus affinity for carbon dioxide.
- Intervention effect The apparent quantum requirement for carbon dioxide reduction was identical in chilled and unchilled plants.
- Intervention effect Chilling reduced tomato leaf water potential by only 1 bar.
- Intervention effect Chilling caused a small secondary loss of chlorophyll.
- Observation Chloroplast activity did not recover during the light period immediately after chilling.
- Observation After light and dark, stomatal conductance recovered more slowly than chloroplast activity.
