Table 8. Pearson’s product-moment correlation coefficients between metabolite concentration and SPAD and Fv/Fm across all temperature and genotype data.

The top six metabolites showing the greatest decrease in metabolite concentration in heat stressed plants compared to control plants were selected for correlation.
