Clone-Specific Response in Leaf Nitrate Reductase Activity among Unrelated Hybrid Poplars in relation to Soil Nitrate Availability
Figure 5
Relationship between concentration observed following a 24 day incubation period in riparian soils and nitrate reductase activity (NRA) for clone DxN-3570 () and MxB-915311 (). NRA values in this figure were obtained by averaging NRA values of the mid-July and late August assays.
