Other claims from this paper (6)
- Intervention effect Diphenylcarbazide restored the inhibited PSII activities.
- Mechanism The authors inferred that cadmium inhibits PSII at the oxygen evolving site between water and Y.
- Intervention effect Maize chloroplast PSI activity was insensitive to cadmium.
- Intervention effect Cadmium decreased total chlorophylls by 20% to 30%.
- Intervention effect Cadmium decreased the Ch1 a/Chl b ratio by 15% to 25%.
- Intervention effect Cadmium decreased the ratio of short to long wavelength Chl a forms by 20% to 25%.
