FIGURE 5. Principal component analysis (PCA) performed with the pollen metrical variables from hybrid (Goydirola) and parental species (Goyazia petraea and Mandirola hirsuta) studied. Goy = Goyazia petraea; Man = Mandirola hirsuta; EDPV = equatorial diameter in polar view; PDEV = polar diameter in equatorial view; EDEV = equatorial diameter in equatorial view; ECLG = ectoaperture length; ECWD = ectoaperture width; ENLG = endoaperture length; ENWD = endoaperture width; EXIN = exine total; SEXI = sexine; NEXI = nexine; SHAP = shape; P.A.I = polar area index; WCI = width colpus index.
