Table 5.

Ring width, latewood width, and radial cell width (RCW) of earlywood (EW) and latewood (LW) cells in 2007 and 2008 at study plots (n = five trees/site, mean values ± standard deviation). Statistically significant differences of mean values between sites are indicated by different letters (P < 0.05; Student's t test).
