Figure 3

PCA biplot of the germination data under control (a) and drought stress (b). Dark-green 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 pink triangles indicate the barycentre of the six ornamental species. The magenta rhombus indicated the barycentre of the drought-stress treatments. The amount of variation explained by each principal component, PC1 and PC2, is indicated in parenthesis. Sle seed length, Swi seed width, SE seed weight, GP germination percentages, MGT mean germination time, FGD first germination day, LGD last germination day, SE speed of emergence, GI germination index, TSG time spread of germination, RadL radicle length, HypL hypocotyl length, rRadL radicle length reduction, rHypL hypocotyl length reduction, SVI seedling vigour index.
