The feasibility of using the wavelength of the maximum slope of the red edge of leaf reflectance spectra (λre) as an indication of plant chlorophyll status was examined in the laboratory for single leaves of several species. λre for each sample was determined by derivative reflectance spectroscopy. A high positive correlation was found between λre and leaf chlorophyll content for all species, although there were some differences in the quantitative nature of the relationship for plants of different types. The position of the red edge was found to be unaffected by simulated change in ground cover, but multiple leaf layers produced a shift in its position. Appropriate spectral measurements and processing for obtaining useful information from the red edge are discussed, and the potential of the red edge in relation to other spectral measurements is considered. 相似文献

Work has been carried out to elucidate fundamental relationships between spectral properties of plants and geochemical stress, and a programme of field and laboratory work is in progress. The most significant results and conclusions at this stage are described and attention is focused on the new concepts for stress detection which have been generated. The applications of the research are relevant to the understanding of current remotely sensed data as well as relating to ideas for new instrumentation. 相似文献
