Fig. 5From: Localization of polyhydroxybutyrate in sugarcane using Fourier-transform infrared microspectroscopy and multivariate imaging a Infrared spectra of wild-type sugarcane corresponding to the regions identified by the colored circles in Fig. 3b. b Infrared spectra of polyhydroxybutyrate-containing sugarcane corresponding to the regions identified by the colored circles in Fig. 4b. The red spectrum was spatially offset to facilitate a qualitative spectral analysis. All spectra were collected using 256 scansBack to article page
