Other claims from this paper (9)
- Association Predicted CO2 sensitivity of production depended strongly on the assumed relationship between foliar and heartwood nitrogen.
- Intervention effect With constant heartwood nitrogen, changing CO2 produced only a slight predicted growth response.
- Association Predictions were only slightly affected by assumptions about nitrogen retranslocation.
- Association Predictions were only slightly affected by assumed nitrogen effects on specific leaf area and leaf longevity.
- Association Predictions were only slightly affected by carbon allocation among plant parts.
- Association Predictions were only slightly affected by changes in the N:C ratio of passive soil organic matter.
- Association Changing the foliar nitrogen effect on light utilization had only a small effect on pine CO2 sensitivity.
- Association The pine prediction depended strongly on the assumed relationship between leaf photosynthesis and leaf nitrogen.
- Intervention effect The analysis suggested substantial growth increases in nitrogen limited trees under rising atmospheric CO2.
