Large Planting Stock Type and Mechanical Release Effects on the Establishment Success of Picea glauca Plantations in Quebec, Canada

Figure 6

Profile of height/ground-level diameter ratio over eight growing seasons of large Picea glauca seedlings outplanted in south central Quebec (Canada). (a) Presents height/ground-level diameter ratio for each of four vegetation management treatments that were compared. Treatments consisted of four intensities of vegetation management, including a control, mechanical release during the third growing season (REL3), mechanical release during the fifth growing season (REL5), and plots where competition for light was eliminated through repeated herbicide and mechanical release treatments (No competition: NC). (b) Presents height/ground-level diameter ratio by stock type.
