Maintenance respiration of attached fine roots was measured on mature loblolly pine and sweetgum (Liquidambar styraciflua ) growing in atmospheric CO2 elevated by 200 mu1 1 -1 above ambient. Fine root maintenance respiration on a mass basis was significantly lower in the elevated CO2 treatment for loblolly pine, but was not significantly different for sweetgum. Annual growth respiration was significantly higher in the elevated CO2 treatment for loblolly pine because of significantly greater construction respiration and fine root production.
