Other claims from this paper (16)
- Intervention effect Cu stress significantly reduced leaf chlorophyll content.
- Intervention effect Cu stress significantly decreased Fv/Fm.
- Intervention effect Zn treatment did not affect Fv/Fm.
- Observation Leaf PIABS was sensitive to both Cu and Zn stress.
- Intervention effect Cu stress weakened PQ electron acceptance, damaged OEC and inhibited QA- to QB electron transfer.
- Intervention effect Zn stress weakened PQ electron acceptance, damaged OEC and inhibited QA- to QB electron transfer.
- Intervention effect Cu stress dissociated leaf thylakoids.
- Intervention effect Zn stress did not significantly damage leaf thylakoids.
- Association Under Cu and Zn stress, reduced RC/CSm significantly increased ABS/RC and TRo/RC.
- Association DIo/RC increased as stress intensified, indicating greater heat dissipation.
- Intervention effect Cu stress significantly increased leaf O2- production, H2O2 content and MDA accumulation.
- Intervention effect Zn stress had minimal effect on ROS production and oxidative damage.
- Intervention effect At 800 μmol·L−1, Zn stress increased O2- production.
- Intervention effect Cu stress increased SOD, POD, CAT, APX and GPX activity.
- Intervention effect Zn stress enhanced SOD and GPX activity.
- Observation Cu caused significantly more photoinhibition and oxidative damage than Zn.
