General flowering-plant evidence on apical dominance, axillary bud release, auxin transport, cytokinin, strigolactone, sugars, and the limits of single-signal explanations for shoot branching.
Visual lesson 07
Axillary bud activation
Separate the presence of an axillary meristem or bud from later bud release and elongation, then connect sustained branch outgrowth to developmental signaling, light, assimilate availability, sink competition, and the state of neighboring shoots.

PracticeCan you explain what the visual is showing?
What is the most important distinction between an axillary bud being present at a node and that bud producing an elongating branch?
