Effects of Competition, Drought Stress and Photosynthetic Productivity on the Radial Growth of White Spruce in Western Canada.

With an increase in the drought code, there was a decrease in average radial growth (Figure 2C ; r P = −0.288, p = 0.058) and an increase in transect basal area (Figure 2D ; r P = 0.293, p = 0.054) but these relationships were not quite significant.
