Other claims from this paper (11)
- Association Parallel venation had no significant effect on Abt465 in banana.
- Association Parallel venation had no significant effect on Abt465 in Doryanthes.
- Association Parallel venation had no significant effect on Abt465 in a Dendrobium orchid.
- Association Parallel venation had no significant effect on Abt465 in pineapple.
- Association Parallel venation had no significant effect on Abt465 in sugarcane.
- Association In the fern A. nidus there was a slight difference in Abt465 related to parallel venation.
- Observation Average leaf absorptance at 465 nm (Abt465, about 0.96) was about 14% higher than the standard value of 0.84.
- Observation Average leaf absorptance at 625 nm (Abt625, about 0.89) was about 6% higher than the standard value of 0.84.
- Observation The PAR-range absorptance Abt400-700 (about 0.88) was only about 5% higher than the standard value.
- Observation In some species such as water lily, absorptances at blue and red wavelengths are quite different.
- Recommendation Reflectance measurements of leaves with the RAT would also be useful for remote sensing studies.
