Molecular functional group images of the wheat seed tissue from the pericarp (outside), seed coat, aleurone layer and endosperm. From left to right: visible image; chemical image; spectra corresponding to the pixel at the cross-hair in the visible image (spectrum pixel size 10 µm × 10 µm). Area under (a) 1732 cm−1 peak (carbonyl C=O); (b) 1515 cm−1 peak (aromatic compound); (c) 1650 cm−1 peak (amide I); (d) 1025 cm−1 peak (starch); (e) 1246 cm−1 peak (cellulosic materials). |
