Fig. 2From: Changes in the sugars, amino acids and organic acids of postharvest spermine-treated immature vegetable soybean (Glycine max L. Merr.) as determined by 1H NMR spectroscopyHeatmap of effect of exogenous spermine on metabolite profiles of cold-stored immature vegetable soybeans. Red colour indicates higher metabolite concentration than the median of the samples, blue indicates a lower concentration. The metabolites are listed on the right side of the heat map with metabolite clustering on the left. All samples are listed on the top of the map as well as the sample clustering treeBack to article page
