X-ray analysis can be used to determine the quality of seeds, showing the cause of bad germination. X-ray images provide information on the internal structure and morphology of seeds, mechanical damage, percentage of empty and filled seeds, microfractures, possible embryo deformations and insect infestation. These techniques has been developed in Cuba for different X-ray sets. In this article we describe the suitable working conditions for 32 agricultural and forestry species. We also explained the main damages to seeds and their consequences for germination. If affected by insects, it could reduce the storage ability of grains.
