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 2: Average (the curves) and standard deviation (the shaded area) of reflectance spectra of adaxial and abaxial leaf surfaces for (A) white poplar (n=55) and (B) Chinese elm (n=60). λ is the wavelength.

Mentions: The reflectance spectra for adaxial and abaxial surfaces of white poplar and Chinese elm are presented in Fig. 2. It is apparent that the reflectance spectra were much lower in the visible wavelengths (400–680nm) for the adaxial surface than for the abaxial surface. However, the difference in the near infrared (NIR) wavelengths (760–1000nm) was not significant. Furthermore, the difference between the spectral reflectance of adaxial and abaxial surfaces for the white poplar leaf (Fig. 2A) was significantly greater than that for Chinese elm (Fig. 2B) in the visible wavelengths.
