Clone-Specific Response in Leaf Nitrate Reductase Activity among Unrelated Hybrid Poplars in relation to Soil Nitrate Availability

Figure 1

Linear relationships between soil supply rate and soil tube in situ incubations in riparian soils for 3 variables: (a) initial concentration in soil tube soils prior to incubation, (b) final concentration in soil tube soils following a 24 day incubation period, and (c) nitrification rate in soil tube soils during a 24 day incubation period. All relationships are significant at .
