X-ray analysis can be used to exam the inner structure of a seed for mechanical damage, absence of vital organs such as embryo or endosperm, insect infestation, cracked or broken seed coats, and shrinkage of interior tissues that might signal extreme age.

The major advantage of this technique is that it is a non-destructive method of evaluating seeds.
