Cannabis leaf morphogenesis, phyllotaxy, plant architecture, reproductive transition, inflorescence development, trichome development, and senescence across a complete life cycle.
Visual lesson 09
Phyllotaxy & developmental nodes
Follow documented Cannabis changes in axillary structures, stipules, bracts, solitary flowers, and opposite-to-alternate phyllotaxy across development while treating the published node numbers as genotype- and condition-specific observations rather than a universal Cannabis clock.
