“…The transpiration stream concentration factor, which is the ratio of the concentrations in the xylem and solution, was greater than 1.5 for all compounds except for hydroxybenzotriazole indicating translocation into the xylem of the plant. Interestingly, Dokken et al (2005) used Fourier transformed infrared (FTIR) spectroscopy to study the uptake of benzotriazole by sunflower plants. The FTIR spectra of the roots showed peaks for changes in the lignin structure and the presence of benzotriazole.…”

“…This technique has emerged as a key technique for studying tissue cell-wall components (McCann & Roberts, 1994;McCann et al, 1995McCann et al, , 1997Wetzel et al, 1998;Yu et al, 2004;Dokken et al, 2007), for studying plant growth and development (Dokken et al, 2007;McCann & Roberts, 1994;McCann et al, 1995McCann et al, , 1997, monitoring the fate of organic contaminants in plants (Dokken et al, 2005) and studying the bread-making quality of wheat (Bonwell et al, 2008). Dokken (2006) indicated that current wet chemistry techniques, although helpful, degrade plant tissue resulting in the loss of spatial distribution and the production of artifacts because wet chemistry techniques employ strong chemical processing and extractions such as GC-MS (gas chromatography mass spectrometry) and HPLC (high-performance liquid chromatography). SR-IMS permits direct analysis of plant cell-wall architecture, combining spatially localized information and chemical information from the infrared absorbance to produce a chemical map that can be linked to a particular morphology or functional group (Budevska, 2002;Dokken, 2006;Dokken et al, 2007).…”

Dokken (2006) showed that SR-IMS, as an important analytical tool, could be used to determine the fate and effect of organic contaminants in plants.…”

“…The imaging ability of infrared microspectroscopy (IMS) permits the analysis of plant cell wall architecture at the cellular level. The use of synchrotron radiation as an infrared source and the application of chemometric methods, such as principle components analysis (PCA), make IMS a powerful tool for the study of plant growth and development (Dokken et al, 2005a,b,c).…”
