AXILLARY BUD BEHAVIOUR
Could hedging cause exhaustion of flowering and branching sites?
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?
CARBOHYDRATES + 3D STRUCTURE

C. Carbohydrate movement and growth
CARBOHYDRATES + 3D STRUCTURE
• New growth utilisation of stored vs newly synthesised carbohydrates
• Branching angles
