Other claims from this paper (6)
- Association GIR related linearly to NDVI across most of its range.
- Association GIR related linearly to SPAD across most of its range.
- Method / resource NDVI was more sensitive than G/R at low values.
- Method / resource GIR was more sensitive than SPAD above GIR 1.2.
- Observation GIR responded to leaf chlorophyll concentration and leaf number.
- Recommendation Digital color imaging was judged useful for measuring canopy senescence.
