Among the most differentially up-accumulated (Table 2) metabolites were Lipids (8 metabolites), Nucleotides/derivatives (4 metabolites), Terpenoids (2 metabolites), and Flavonoids (1 metabolite)

In 2017, the contents of total nitrogen were the highest at 116 DAT, followed by that at 130 DAT and the lowest contents were found at 123 DAT: however, nicotine contents peaked at 123 DAT, followed by 130 DAT and 116 DAT
