A seed is a living organism essentially in suspended animation. Cells in the embryo have intact plasma membranes, DNA repair mechanisms are present (although working very slowly), each cell is surrounded by a cell wall, and the entire seed has an outer protective seed coat.
When people talk about DNA degrading, they are usually referring to DNA that is no longer inside living cells, and that doesn't have these multiple levels of protection.
