Figure 5

The ratio of dry weight of current-year shoots to estimated needle dry weight of 1-year-old shoot (Shoot0-year/Needle1-year) as a function of integrated PPFD during the morning from sunrise to noon (PPFDint), with various rates of canopy tree cutting conducted in October 2015 (open symbols) and January 2016 (closed symbols). Symbols are the same as in Fig. 4. Shoot0-year includes dry weight of needle leaves and stem. The PPFDint was estimated for May 10, 2016 based on a hemispheric photograph taken in July for each plot. Values are means ± standard error (SE) of n = 3–5.
