e0“soybean leaves simultaneously decreased quantum yield and carboxylation efficiency. These decreases were proportional to the accompanying decrease of light-saturated photosynthetic rate under normal atmosphere. ABA did not affect the CO2 compensation point at saturating irradiance, or the stimulation of net photosynthesis produced when the partial pressure of oxygen was reduced from 210 to 20 mPa Pa−1 at a rate-limit…” Show full quote

Other claims from this paper (9)
- Intervention effect Abscisic acid decreased quantum yield in attached soybean leaves.
- Intervention effect Abscisic acid decreased carboxylation efficiency in attached soybean leaves.
- Intervention effect The decreases in quantum yield and carboxylation efficiency were proportional to the decrease in light-saturated photosynthetic rate.
- Intervention effect Abscisic acid did not affect the CO2 compensation point at saturating irradiance.
- Intervention effect Abscisic acid did not alter the net photosynthesis stimulation caused by reducing oxygen partial pressure at rate-limiting irradiance.
- Intervention effect The activation status of RuBP carboxylase was insensitive to abscisic acid.
- Intervention effect Abscisic acid decreased photosynthetic capacity in soybean leaves.
- Intervention effect The increase in RuBP content was proportional to inhibition of photosynthetic capacity.
- Intervention effect Photosynthetic rate of abscisic-acid-treated leaves did not increase after irradiance rose within the light-limited range.
