Score scatter pots of the two PCA models obtained with root exudates collected after 3 and 6 h. PCA model for samples collected at 3 h (R2X = 0.530, 5 PCs; scaling: mean-centering and unit variance scaling) from Fe-sufficient (Fe+) and Fe-deficient (Fe−) microcuttings of Ramsey and 140R rootstocks. PCA model for samples collected at 6 h (R2X = 0.527, 5 PCs; scaling: mean-centering and unit variance scaling) from Fe-sufficient (Fe+) and Fe-deficient (Fe−) microcuttings of Ramsey and 140R rootstocks.
