Multiple regression models of each leaf stage. Fresh LMA was included as an additional explanatory variable to CCI and the data of the four Quercus species were pooled. The equations convert the CCI and fresh LMA (g m−2) values into the estimated total chlorophyll content per unit area (mg cm−2). The significance values of both parameters (CCI and fresh LMA) are shown.
