Comparing vegetation indices for remote chlorophyll measurement of white poplar and Chinese elm leaves with different adaxial and abaxial surfaces.

Lu S, Lu X, Zhao W, Liu Y, Wang Z, Omasa K - J. Exp. Bot. (2015)

Bottom Line: The results showed that most of the published VIs had strong relationships with LCC on the one-surface dataset, but did not show a clear relationship with LCC when both adaxial and abaxial surface reflectance data were included.It explained 92% of LCC variation in this research, and the root mean square error of the LCC prediction was 5.23 μg/cm(2).This new index is insensitive to the effects of adaxial and abaxial leaf surface structures and is strongly related to the variation in reflectance caused by chlorophyll content.

Figure 3: Difference in reflectance between adaxial and abaxial surfaces of (A) white poplar and (B) Chinese elm.

Mentions: The differences in reflectance between adaxial and abaxial surfaces are shown in Fig. 3. A distinct difference could be found between the surfaces in the white poplar leaves, but a smaller variation was shown in the Chinese elm leaves, a result which agreed with their leaf surface appearance and microscopic photographs. In white poplar leaves, the least reflectance difference between adaxial and abaxial surfaces occurred at 735nm wavelength and it occurred at 728nm in Chinese elm leaves.
