Figure 4

PCA biplot of the growth data under control (a) and drought stress (b). Dark-blue points show the barycentre of the quantitative variables. The increasing colour intensity indicates the progressive importance of the variables in defining the first two principal components. The violet triangles indicate the barycentre of the six ornamental species. The yellow rhombus indicated the barycentre of the drought-stress treatments. The amount of variation explained by each principal component is indicated in brackets. RL root length, rRL root length reduction, FWr fresh root, rFWr fresh weight reduction, WCr root water content, SL shoot length, rSL shoot length reduction, FWr root fresh weight, rFWr root fresh weight reduction, Lno leaf number, rLno leaf number reduction, WCs shoot water content, Chl A chlorophyll a, Chl B chlorophyll b, Caro carotenoids, Pro proline, TSS total soluble sugars, MDA malondialdehyde, H2O2 hydroxide peroxide, TPC total phenolics compounds, TF total flavonoids.
