Other claims from this paper (8)
- Intervention effect Salt stress caused a significantly smaller decline in net photosynthetic rate in S111-9 than in Glycine max.
- Association The decline in photosynthesis was positively related to declines in stomatal conductance and intercellular CO2 in S111-9.
- Association The decline in photosynthesis was related to stomatal conductance in G. max.
- Intervention effect Increasing salinity significantly reduced photochemical quenching, open PSII-center efficiency and Rubisco activity in G. max.
- Intervention effect The highest NaCl level significantly reduced maximum PSII quantum yield in both varieties.
- Mechanism The larger Rubisco activity reduction in G. max was attributed to Rubisco content, regulated mainly at LSU expression level.
- Mechanism The authors attributed salt-induced photosynthesis reduction mainly to stomatal conductance in S111-9.
- Mechanism The authors attributed salt-induced photosynthesis reduction mainly to Rubisco activity in G. max.
