Fig. 2. Scatter diagram of the first two principal coordinates from principal component (PC) analysis (A) and ward cluster (B) for the 31 populations based on needle traits of Pinus yunnanensis, P. kesiya var. langbianensis and P. kesiya. LSC, length of the stomata cavity; LSGC, length of stomata guard cell; NL, needle length; SD, stomatal density; WSC, width of the stomata cavity; WSGC, width of the stomata guard cell; WTLL, length of the woody thickening layer; WTLW, width of the woody thickening layer. See Table 1 for abbreviations of population ID.
