Other claims from this paper (7)
- Method / resource Epifluorescence estimated relative chlorophyll content through spinach leaf tissues, and the leaf cross-section fluorescence profile corresponded to chlorophyll content measured in leaf paradermal extracts.
- Observation Fluorescence profiles across spinach leaves peaked at a depth of 50–70 µ m.
- Association Fluorescence profiles across spinach leaves depended on wavelength and orientation.
- Observation Pathlengthening in the palisade and spongy mesophyll of spinach leaves had similar values.
- Association Pathlengthening in spinach leaves was greatest for green light.
- Method / resource Light profiles within spinach leaves were well approximated by an apparent extinction coefficient and the Beer–Lambert/Bouguer laws.
- Observation Fifty percent of blue and green light reached 125 and 240 µ m deep in spinach leaves, respectively.
