Multispectral and X-ray images for characterization of Jatropha curcas L. seed quality. Plant Methods 17, 9 (2021). https://doi.org/10.1186/s13007-021-00709-6 This paper is demonstrating the importance and high performance of spectral imaging as a fast, non-destructive and versatile tool for assessing seed germination attributes. It concludes: "Multispectral and X-ray imaging have a strong relationship with seed physiological performance. Reflectance at 940 nm and X-ray data can efficiently predict seed quality attributes. These techniques can be alternative methods for rapid, efficient, sustainable and non-destructive characterization of seed quality in the future, overcoming the intrinsic subjectivity of the conventional seed quality analysis."
