I’m not so sure about the “compression only” thing in conifers. It’s a law of physics that if the bottom of the branch is in compression, the top will be in tension; otherwise, “static equilibrium” is violated (all forces add to zero. If there is a force not countered by an equal and opposite one, there will be an acceleration, per Newton’s laws).

I do know that the reaction woods of the conifers and hardwoods have different characteristics, but I don’t remember what they are, or where I read it.
