Figure 1

The dormancy-active growth transition induced by photoperiod and chilling in poplar. a-b: a poplar tree in active growth (a) and its stem cross section showing the anatomical features of active cambial cells (b); Magnification of the stem apex was shown in the insert picture between (a) and (b); c-d: the endodormancy state induced by SD treatment for 8 weeks (c) and the stem cross section showing the anatomical features of cambial cells in endodormancy (d); Magnification of a dormant apical bud was shown in the insert picture between (c) and (d). e: the trees growing in LD for 3 weeks after chilling treatment of 1-5 weeks (C1 to C5), showing the effects of different chilling treatments on the dormancy-release. f-g: the cross sections of stem C1 (f) and C5 (g); h: a statistical chart for cambial cell layers through a SD treatment for 8 weeks. i: a statistical chart of bud sprouting percent for the dormancy-release after chilling treatment for 5 weeks, A bud sprouting was shown in the insert figure in (i). SD1-8: short day treatment for 1-8 weeks; LD: long day; C1-C5: chilling treatment for 1-5 weeks; Ph: phloem; Ca: cambium; Xy: xylem; bars = 100 μm.
