Fig. 2 in Profiling of volatile and non-volatile metabolites in Polianthes tuberosa L. flowers reveals intraspecific variation among cultivars

Fig. 2. Heat map representing the diversity of nonvolatile compounds detected in P. tuberosa flowers. Floral extracts after derivatization were analysed by GC-MS. Classes 0, 1, 2, 3, 4, 5, and 6 indicates group average abundances of Calcutta double, Calcutta single, Jyothi, Ujwal, Shnigdha, Shringhar, and Phule rajani cultivars respectively. Red and green color denotes highest and lowest relative abundances of non-volatile compounds, respectively. Abbreviations: Met a-D-gal - Methyl α-D-galactofuranoside, Met b-D-gal - Methyl β-D-galactopyranoside, Met b-D-glu - Methyl β-D-glucofuranoside, 4- HBALD - 4-hydroxybenzaldehyde, 4-HBA - 4-hydroxybenzoic acid, 2, 5-DHBA - 2, 5-Dihydroxybenzoic acid.
