Polysaccharides are the major bioactive components of Polygonatum cyrtonema Hua, and their biosynthesis accumulation influenced by many agronomic practices. In this study, we applied integrative metabolome transcriptome analyses to investigate in one-year-old (1Y) six-year-old (6Y) rhizomes P. Hua treated with a plucking flower. The compound content analysis suggested that (T6) accumulated highest polysaccharide compared (T1), untreated (C1), (C6). Metabolomics showed 4-O-galactopyranosylxylose, 6-O-α-l-arabinopyranosyl-d-glucopyranose, d-arabinose dl-xylose significantly T6 rhizomes. Carbohydrate metabolic pathways, including "glycolysis/gluconeogenesis", "pentose glucoronate interconversions" "amino sugar nucleotide metabolism" were highly correlated accumulation. data indicated UPG2, GPI, GALE positively upregulated T6_vs_C6. parallel, RHM PEI down-regulated Taken together, study not only indicates candidate metabolites/metabolic pathways genes affected flowers may influence polysaccharides but also provides an easy feasible practice facilitate Hua.
