Title
Acclimation of shade-developed leaves on saplings exposed to late-season canopy gaps
S. L. Naidu; E. H. DeLucia Tree Physiology 1997. doi:10.1093/treephys/17.6.367
Other claims from this paper (6)
- Intervention effect Photosynthetic rates rose in shade leaves of both species after canopy gap exposure.
- Observation Red oak had more complete final acclimation.
- Observation Both species experienced short-term reductions in maximum net photosynthesis and oxygen evolution quantum yield.
- Observation Both species experienced longer-term reductions in PSII excitation capture and light quantum yield.
- Association Photosynthetic acclimation appeared linked to increased leaf nitrogen.
- Mechanism Limited sugar maple acclimation may reflect a tradeoff with shade tolerance.
