anova table showing main effects and interactions of date (D), warming (W) and litter addition (L) on the emissions of isoprene (I), total monoterpenes (MT), total sesquiterpenes (SQT) and total of other VOCs in the actual (A) emissions and emission potentials (S). P-values for the main and interaction effects included in the model are shown
