Changes of non-enzymatic and anthocyanin accumulation in potato leaves, phenolics (A), flavonoids (B), proline (C) and anthocyanin (D) in C (control), KPhi (leaves treated with KPhi), CPi (control leaves inoculated by P. infestans), KPhiPi (leaves inoculated three days after KPhi application). Means not sharing a common letter within the same letters in the graph are significantly different at p < 0.05 according to Tukey’s test.
