Figure 2 : Performance variables of Taraxacum officinaleplants from nine introduced populations collected along a latitudinal gradient in Chile that were grown in soil with three manipulated microbiome treatments: control unsterilized soil [M+], sterilized [M-], and sterilized and reinoculated [Mr]). Performance was estimated in terms of a) survival (%), b) biomass (g) and c) number of flowers (n). In addition, a combined response was also calculated through an integrated “performance index” (d). The ”overall performance” variable is estimated through an integrated “performance index” (See Materials and Methods). The solid trend line and the shadow areas constitute the best fit of the corresponding LMM model and their respective confidence intervals (95 %). Each point corresponds to a …
