Don't abuse capital letters.

What matter property is responsible for these patterns? Do amorphous substances have this property?

It is not exactly true amorphous compounds show no difraction. But of course they do not show such regular diffraction patterns as monocrystals.

see, eg classical book: A. Guinier, X-Ray Diffraction in Crystals, Imperfect crystals and Amorphous Bodies
