ResumoThis work explores the continuum removal (CR) technique to detect plant stress in visible/near infrared wavelengths. The red edge of the 680 nm chlorophyll absorption is a key feature in plant stress studies (e.g., [1], [8], [7]). The CR transformation consists of estimating the absorptions not due to the band of interest and removing their effects [2]. The CR technique normalises the reflectance spectrum and isolates absorption features to allow comparison between absorption bands on a common basis [4]. The CR method was initially used in geological remote sensing and was first applied to studies of leaf biochemistry by [5]. [6] demonstrated that the distinction between healthy and contaminated plant samples was improved when analysing the continuum-removed reflectance compared to reflectance and first derivative of reflectance data. In that study, they applied the CR using fixed continuum channels (e.g. 550-570 nm). Pre-stipulated wavelengths (i.e. left and right channels) used to determine the continuum line for the CR of a specific absorption feature can be adjusted for each sample to better represent the feature (PRISM software, [3]). In the present study, a time series of close range canopy reflectance data of a grass plant species (Brachiaria brizantha) grown in liquid hydrocarboncontaminated (diesel DSL; gasoline-GSL) soil was acquired with a portable spectrometer (ASD FieldSpec® 3 Hi-Res). The parameters describing the chlorophyll 680 nm absorption feature (continuum channels, depth, width, and area) were derived using the CR applied to the spectra using fixed (FIX) and adjusted (ADJ) continuum channels. Differences between CR-FIX and CR-ADJ results are observed in Figure 1 for all parameters but the feature centre (Table 1). Left and right channels of the continuum line differs some 16 nm and 8 nm on average, respectively, for the FIX and ADJ methods. In addition, the mean depth, width (FWHM full width at half maximum) and area of the 680 nm feature yielded with the ADJ technique showed higher values. The analysis of the parameters estimated for the 680 nm absorption feature (CR-ADJ) for each of the contamination treatments, indicates that plants stressed by DSL and GSL display mean values of depth, width and area substantially lower than healthy plants (CTR) (Table 2). The results imply that to better characterize an absorption feature, the application of the CR technique using adjusted channels is superior and should be favoured in the analysis. Plant stress in brachiaria grass induced by the contamination of soil with DSL and GSL can be detected with spectral feature analysis focusing on the depth, width or area of the 680 nm chlorophyll absorption feature.

ResumoThis paper explores the use of spectral feature analysis to detect plant stress in visible/near infrared wavelengths. A time series of close range leaf and canopy reflectance data of two plant species grown in hydrocarbon-contaminated soil was acquired with a portable spectrometer. The ProSpecTIR-VS airborne imaging spectrometer was used to obtain far range hyperspectral remote sensing data over the field experiment. Parameters describing the chlorophyll 680. nm absorption feature (depth, width, and area) were derived using continuum removal applied to the spectra. A new index, the Plant Stress Detection Index (PSDI), was calculated using continuum-removed values near the chlorophyll feature centre (680. nm) and on the green-edge (560 and 575. nm). Chlorophyll feature's depth, width and area, the PSDI and a narrow-band normalised difference vegetation index were evaluated for their ability to detect stressed plants. The objective was to analyse how the parameters/indices were affected by increasing degrees of plant stress and to examine their utility as plant stress indicators at the remote sensing level (e.g. airborne sensor). For leaf data, PSDI and the chlorophyll feature area revealed the highest percentage (67-70%) of stressed plants. The PSDI also proved to be the best constraint for detecting the stress in hydrocarbon-impacted plants with field canopy spectra and airborne imaging spectroscopy data. This was particularly true using thresholds based on the ASD canopy data and considering the combination of higher percentage of stressed plants detected (across the thresholds) and fewer false-positives.
