Plastic Response of Tracheids in Pinus pinaster in a Water-Limited Environment: Adjusting Lumen Size instead of Wall Thickness
Fig 4
Standardized tracheidograms for the four years (2010–2013).
The number of tracheids per ring was set to 25 and each standardize tracheidogram contains 16 tracheids in earlywood (Ew) and 9 in latewood (Lw). A) Lumen diameter (LD); B) Cell wall thickness (CWT); C) Ratio of LD to CWT (LD/CWT). The color lines represent the means and the shaded areas the 95% confidence intervals.
