a Absorption FTIR spectra of the cell wall in the 4000–400 cm-1 and 1800–800 cm-1 regions. b Transverse sections of 8 µm thickness were stained with phloroglucinol-HCl, which selectively stains lignified cell walls. Bars, 100μm. FTIR, Fourier-transform infrared spectroscopy; S1, flower-bud stage; S2, pigmented stage; S3, unfold-petal stage; S4, full-flowering stage
