Other claims from this paper (11)
- Intervention effect Cadmium significantly lowered the chlorophyll a/b ratio.
- Intervention effect Later cadmium treatment inhibited chlorophyll accumulation in vigorously growing young leaves.
- Intervention effect Later cadmium treatment decreased the chlorophyll a/b ratio only in vigorously growing young leaves.
- Intervention effect Lead had only slight effects on chlorophyll content and a/b ratio.
- Intervention effect Cadmium reduced chlorophyll-containing complexes most for photosystem I and least for photosystem II core.
- Observation Under lead, light-harvesting complex II appeared more sensitive than photosystem I.
- Observation Long-wavelength chloroplast fluorescence declined or shifted blue.
- Association Chlorophyll and chlorophyll-protein accumulation showed no close relationship with leaf heavy-metal content.
- Observation Leaf heavy-metal content was highest in the first intensively expanding leaves at treatment.
- Observation Cadmium treatment showed exceptional photosystem I sensitivity and relative photosystem II stability.
- Association Cadmium-treated leaf chlorophyll patterns followed manganese-content changes.
