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 02
Apical dominance
Understand how the active shoot apex can suppress lateral bud outgrowth through systemic signaling and resource relationships, and why removing or repositioning the apex can change branching without guaranteeing one fixed response.
Interactive academic visual

Shoot position and hormonal signaling influence lateral bud growthShoot apex
The active shoot apex strongly influences the growth behavior of axillary buds below it.
