From left to right, the heatmap shows (1) Name of the compounds, (2) chemical classes of the compounds, and (3) amount of the compounds in headspaces at different phenological stages (flower, immature fruit, and mature fruit) of C. mixta, C. pepo and C. sativus respectively. Volatiles are arranged in descending order based on sharedness. The relative abundance (surface area of GCMS peak) of the compounds represented by a gradient from light blue (lowest) to red (highest). Cas numbers of compounds shown in red text were confirmed via synthetic injection.
