Table 2. Pearson's correlation coefficients between chlorophyll concentration and relative gene expression during tuber greening of ‘Nicola’ (greening-resistant variety) and ‘Kennebec’ (greening-susceptible variety). The symbols *, ** and *** represent statistical significance at p<0.05, p<0.01, and p<0.001, respectively.
