- Intervention effect The lowest supplemental UV-B reduced seedling growth after one month.
- Intervention effect The lowest supplemental UV-B reduced photosynthetic capacity after one month.
- Intervention effect Those initial reductions persisted and biomass production was lower.
- Intervention effect Lowest supplemental UV-B did not increase needle UV-B absorbing compounds.
- Intervention effect At simulated 25% ozone reduction, UV-B absorbing compounds increased after six months.
- Intervention effect At simulated 25% ozone reduction, photosynthesis recovered after an initial decrease.
- Intervention effect At simulated 25% ozone reduction, growth recovered after an initial decrease.
- Intervention effect At the highest UV-B irradiance, absorbing compounds increased more rapidly.
- Intervention effect Highest UV-B irradiance had no growth effect until after four months.
- Intervention effect Highest UV-B irradiance had no photosynthetic capacity effect until after four months.
- Intervention effect UV-B had no observed effect on stomatal conductance.
