Other claims from this paper (6)
- Observation Excitation energy transfer efficiency in mistletoe sun leaves was markedly reduced in winter.
- Observation A 715 nm fluorescence band emerged in winter mistletoe leaves.
- Observation A 705 nm fluorescence band appeared as the PSII band declined.
- Mechanism Shorter fluorescence lifetimes indicated enhanced thermal energy dissipation.
- Observation Winter photosynthetic acclimation symptoms were stronger in mistletoe sun leaves than eucalypt sun leaves.
- Mechanism The authors attribute enhanced winter acclimation symptoms mainly to limited photosynthetic capacity of A. miquelii.
