Anatomical and histochemical analyses in Populus trichocarpa stems of different developmental stages. a An illustration of stem segments in a 90-day-old Populus trichocarpa sample plant used as study material. The number of each internode (IN) is indicated from the apical bud to the base of the stem. b, e, and h represent toluidine blue O-stained transverse sections from the internodes two (IN2), four (IN4), and eight (IN8), respectively. c, f, and i are phloroglucinol-HCl-stained transverse sections from IN2, IN4, and IN8, respectively. d, g, and j represent calcofluor white-stained transverse sections from IN2, IN4, and IN8 under UV light, respectively. The arrowheads represent changes in xylem of P. trichocarpa stems. Scale bars = 200 μm
