(a) PCA analysis of Narvik (G1) and Gružanski zlatni (G2) tomato cultivars, grown in the polytunnel without (C) or with T. harzianum application (T), involving: fruit weight (FW (cm 10⁻²)), fruit height (FH (cm 10⁻²)), number of fruit per plant (FN), fruit mass (FM (g)), total polyphenols (TP (GEA mg/100 gDW)), total flavonoids (TF (mg/100 gDW)), starch (S (mg/g DW)), contents of soluble sugars (SS (mg/g DW)), macroelements N (%), P (ppm), K (ppm) and heavy metals (ppm): Mn, Fe, Cu, Zn, Ni, Cr, Pb, and Co. (b) Correlation matrix (Pearson´s product correlation coefficient) with the associated p value between the principal components and the analyzed variables.
