Table 4

Results of the ANOVA on the needle traits according the two models: No. 1 with tree as a single effect and No. 2 with the effects of species and tree nested within SPECIES in the model. DF is degrees of freedom. R2 is proportion of variance explained by the model. CV is the coefficient of variation.
