Response of , (L.) Karst. provenances to aluminum in hydroponicsseed stands. Al concentration in the needles was negatively correlated with the growth traits. Exposure to Al caused a decreased uptake of several nutrient elements; Ca, Mg were affected mostly whereas K and P uptake were slightly reduced by Al. An intraspecific variation in element concentration was, with the exception of K and Al, not observed.

For the SSB provenance there was no difference in needle wax degradation between trees grown at Vallombrosa (with high levels of pollution) and those grown in Calabria (with negligible pollution).
