Cannabis sativa stem morphology and cross-sectional anatomy, including peripheral bast fiber bundles, xylem-rich inner tissues, lignification gradients, internode traits, and genotype-dependent structural variation.
Visual lesson 08
Bast fibers & structural support
Locate cellulose-rich bast fiber bundles toward the stem periphery and the more lignified xylem-rich inner core, then connect tissue position, maturation, and cell-wall composition to mechanical support.
