Pearson’s correlations between upper plot (UP) and lower plot (LP) proewhitened chronologies representing (a) differnet growth descriptors and volume increment of (b) basal area group and (c) age cohorts. All correlations had P < 0.001. See text for acronyms explanation. Calculation period: 1974–2006. All correlations significant with P < 0.001.
