Female cannabis phytomer organization, solitary flowers, branching, photoperiod response, inflorescence architecture, and floral development.
Visual lesson 02
Flower initiation
Follow solitary pistillate flower initiation and early reproductive phytomer development while distinguishing those events from the later condensation of the whole inflorescence.
Interactive academic visual
Flower initiation
Follow structural transition from preflower expression into expanding floral sitesPreflower at node
Early reproductive structures appear near nodes before dense flower clusters develop.
