Xylem conduit diameter (a), xylem area (b), non-collapsed phloem area (c), last xylem ring area (d), non-collapsed phloem: xylem area (e), and non-collapsed phloem:last xylem ring area (f) of A. fargesii seedlings at 2600 m, 2900 m and 3200 m altitudes (n = 10 branches per elevational site). Boxplots show the median (horizontal bar), interquartile range (box), range (lines), and outliers (points). Mean values are indicated by small square. Different letters indicate significant differences (P < 0.05) among elevations according to Tukey’s multiple-comparisons method
