文摘
- •
An elevation gradient was used to test tree health indicators in Trentino, Italy.
- •
Crown transparency, productivity and leaf traits were compared on Picea abies trees.
- •
A significant effect of elevation was consistently detected by all the indicators.
- •
Shoot length, needle weight, FV/FM, δ18O decreased when crown transparency increased.
- •
This pattern is partly independent from the effect of elevation.
