Other claims from this paper (7)
- Observation Cotton grown at elevated CO2 had large starch pools and visible physical damage.
- Intervention effect After transfer from 1000 to 350 microliters per liter CO2, cotton leaf-area photosynthetic rates recovered to the 350-grown control level within four to five days.
- Intervention effect Cotton photosynthetic efficiency recovered to the 350-grown control level within three to four days.
- Association Recovery of cotton photosynthesis correlated with rapid depletion of starch pools.
- Mechanism The authors attributed cotton photosynthetic inhibition primarily to feedback inhibition associated with starch depletion.
- Mechanism The authors proposed that complete recovery may involve repair of chloroplast damage caused by excessive starch accumulation.
- Mechanism The authors suggested strong sinks at developmental stages could reduce starch accumulation and restore near-theoretical photosynthesis during high photosynthate demand.
