The prefix 'pykno-' denotes which characteristic?

Dense. The prefix pykno- comes from Greek pyknos meaning dense or compact, and it’s used to signal something tightly packed or condensed. In pathology you see this in pyknosis, where the nucleus becomes smaller and chromatin condenses, giving a dense appearance. So the characteristic described by the prefix is density, not softness, lightness, or thinness.
