Do axillary buds have a fixed fate determined at formation ? OR is their behaviour dependent on environment?

AND how?

A. Temperature – sequence of exposure

Inflorescence numbers and temperature sequence

B. Patterns in location

Distribution of inflorescences within growth units

Distribution of inflorescences among growth units

Distribution of inflorescences among stems

Continuing investigations

A. Temperature

– time of floral initiation

B. Location

– stem patterns

– plastic with pruning

– related to formation?
