Table 2 Characteristics of the trees and cores used in this study. DBH and height are referred to the year when the trees were sampled, TRW = tree-ring width, EWDI = earlywood density index, LWDI = latewood density index, MWDI = mean wood density index, LER = latewood to earlywood ratio. min, mean, max, and CV are the minimum, mean, and maximum values and coefficient of variation of each variable, respectively
