Hypothesis
Aquilegia formosa will likely flower in response to long days and vernalization, similar to Arabidopsis.
Conclusion
Vernalization is critical to flowering in Aquilegia formosa, while photoperiod has little or no effect.
Supporting Evidence
- Aquilegia formosa has a strong vernalization requirement but little or no photoperiod response.
- The expression patterns of AqLFY and AqAGL24.2 suggest a hypothesis for the development of Aquilegia's determinate inflorescence.
- Vernalization is the primary ecological factor promoting flowering in Aquilegia formosa populations.
Takeaway
Aquilegia formosa needs cold temperatures to flower, and the length of the day doesn't really matter.
Methodology
Plants were grown under controlled conditions with varying photoperiod and vernalization treatments to assess flowering time.
Potential Biases
The use of hybrid varieties may confound results due to atypical phenotypes.
Limitations
The study did not test the effect of vernalizing using long day conditions.
Participant Demographics
F2 hybrids of Aquilegia formosa collected from two populations in eastern California and Nevada.
