文摘
- •
Saturation pulse treatment led to a severe inactivation of photosystem I (PSI).
- •
Low content of active PSI strongly limited linear electron flow and CO2 assimilation.
- •
PSI inactivation caused only minor changes of OJIP kinetics of variable fluorescence.
- •
Amplitude of IP-phase of OJIP rise seemed to be independent of PSI content.
- •
PSI inactivation led to a higher fraction of QB-non-reducing PSII reaction centers.
