Max Edgley, from the University of Tasmania, sent me this updated power point last week.
He looked at physical damage, N levels (low/medium/high), cooling temperature treatments. His preliminary data suggests:
- Physical damage increases red drupelet numbers
- High N application during harvest had higher numbers of red drupelets
- Staged cooling (precooling and cooling) had less red drupelets than just one cooling temperature.
