Transverse stems sections of watered control (a) and girdled tree (b) and drought-stressed control (c) and girdled tree (d). Girdling occurred during earlywood formation on doy 138 in the watered tree and on doy 190, i.e., about 6 weeks after growth cessation (i.e., latewood completely developed) in the drought-stressed tree. Proliferating ray parenchyma cells and tangential resin canals mark time of girdling in the watered (b) and drought-stressed tree (d), respectively (see arrows).
