different tempetures and water availability. when water is scarse the tree grows many new small diamater pipes (xylem) which look darker to us and when water is plentiful the new xylem are few and bigger in diameter appearing lighter in colour. if you cut a tree that grows in a tropical region which doesnt have the above mentioned variations you wont see any growth rings.

Why are redwood trees that are grown in plantations not very decay-resistant?
The short answer is that growth rates are not everything with Redwood. In the growth rings, Redwood allocates tannins that help it resist decay. The closer the rings are together, the higher the concentration of tannins. Second-growth and plantation grown Redwood typically have large growth rings if managed under even-aged conditions, unless they are grown on longer rotations. Larger growth rings have less tannin per area than smaller growth rings. So if Redwood is grown to longer rotations under even-aged management or grown in uneven-aged management regimes, smaller growth rings lead to higher concentrations of the tannins that help it to resist decay.
