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 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 Abscisic acid increased RuBP content in soybean leaves at saturating irradiance under normal atmosphere.
- 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.
