- •
UV damage and growth varied significantly between high- and lowland ecotypes and the stages after UV-B exposure.
- •
UV tolerance was constitutive in highland ecotypes but inducible in lowland ecotypes.
- •
Common ecotypic differentiation reflected a parallel adaptation to local UV environments.
- •
A potential tradeoff between growth and UV tolerance was found.
