Visual lesson 04
Internodal spacing
Connect internode length to developmental stage, genetics, light environment, temperature, and growth rate rather than treating it as a single-variable trait.
Interactive academic visual
Internodal spacing
Spacing reflects genetics, developmental stage, light, temperature and growth rate togetherNodes
Internode length is measured between successive nodes, so comparisons should use equivalent developmental positions.

PracticeCan you explain what the visual is showing?
Why should internodal spacing not be interpreted from one variable alone?
