Other claims from this paper (6)
- Observation Shade leaves had higher chlorophyll content per unit dry weight than sun leaves.
- Observation Shade leaves had greater thylakoid stacking, with more thylakoids per grana stack and larger stacked granum diameter.
- Observation Shade leaves had lower chlorophyll a/b and F 685 / F 735 ratios than sun leaves.
- Observation Shade leaves had lower saturated light intensity for photosynthesis and maximal net photosynthetic rate than sun leaves.
- Observation In both sun and shade leaves, F m/ F o and F 685 / F 735 promptly decreased and then increased slightly during transition to state 2.
- Mechanism The authors suggested energy spillover and lateral migration of LHC II redistributed absorbed light energy between photosystems in both leaf types.
