Quantitative imaging of lipids in rapeseed seeds with different oil content. a, b and c represent the final lipid distribution shown as a gray value (signal intensity), and d, e and f represent the final lipid distribution of seeds shown as a color coded with high oil content seeds, middle oil content seeds and low oil content seeds, respectively. g, h and i represent the original rapeseed seed and the reconstruction of the rapeseed seed. j, k, l and m represent the reconstruction of the seed coat, radicle, inner cotyledon and outer cotyledon. n, o and p represent the distribution of lipids in different tissues of seeds with high, middle and low oil content; 1, 2, 3, 4, 5 and 6 represent seed coat, outer cotyledon, inner cotyledon, radicle, whole seed and seed section, respectively. sc seed coat, oc outer cotyledon, ic inner cotyledon, r radicle
