- Intervention effect When soil phosphorus availability was low, phosphorus uptake was increased by elevated CO(2).
- Mechanism This may have been related to changes in mycorrhizal competition.
- Intervention effect the shoot weight of all pine families was greater at high CO(2) due to increases in rates of photosynthesis.
- Observation due to increases in rates of photosynthesis.
- Observation More dry weight was partitioned to the stems of P. radiata family 20010 and P. caribaea.
- Observation More dry weight was partitioned to the stems of P. radiata family 20010 and P. caribaea.
- Observation At foliar phosphorus concentrations above 1000 milligrams per kilogram (P. radiata) and 700 milligrams per kilogram (P. caribaea), growth did not increase at 340 microliters of CO(2) per liter.
- Observation At foliar phosphorus concentrations above 1000 milligrams per kilogram (P. radiata) and 700 milligrams per kilogram (P. caribaea), growth did not increase at 340 microliters of CO(2) per liter.
- Observation Soluble sugar levels in the same needles mirrored the growth response, but the starch concentration declined with increasing phosphorus.
- Association the starch concentration declined with increasing phosphorus.
- Observation At 660 microliters of CO(2) per liter, shoot weight and soluble sugar concentrations were still increasing up to a foliar P concentration of 1800 milligrams per kilogram for P. radiata and 1600 milligrams per kilogram for P. caribaea.
- Observation The starch concentrations did not decline.
- Recommendation higher foliar phosphorus concentrations are required to realize the maximum growth potential of pines at elevated CO(2).
