Flowering & Reproductive Development
Age-Dependent Preflowers & Developmental Readiness
Solitary preflowers and later large inflorescences are not the same developmental event. Age-dependent floral structures can appear under longer days, while strong short-day induction changes branching and inflorescence development.
Key concepts
- Preflower expression can reflect developmental maturity
- Photoperiod-induced inflorescence development is a larger architectural transition
- Plant age and node development provide context
- Preflowers should not be confused with fully induced flowering
What to measure or observe
- Record node position of first preflowers
- Photograph preflower progression
- Separate solitary structures from expanding inflorescences
- Track photoperiod and plant age together
Common mistakes
- Calling the first preflower day one of full flowering
- Ignoring plant age
- Comparing plants at different developmental stages
- Using stigma presence alone to define crop stage
Visuals this lesson still needs
- Preflower-to-inflorescence sequence
- Node-age map
- Solitary flower versus induced cluster
- Developmental-stage checklist
