Figure 7. Midday leaf water potential (ΨL)
observations across species and stands. Panel (a) is ΨLinterquartile range in each respective stand. Box‐plots show the median
(middle line), interquartile range (box), and maximum/minimum value
(whiskers), except where values exceed 1.5 times the interquartile range
(points). Numbers above boxes are sample size. Panel (b) is mean
interquartile range (\(\pm\)SE) for each species. Bars not sharing the
same uppercase letters denote significant differences across species by
a two-way ANOVA with species and age as fixed factors.
