Are there two actions of light (external coincidence), or just one (internal coincidence)?
control
Phase delay
Phase advance
Short light interruptions of long dark period
Seedlings given 24h light, then either:a. 48 h dark, orb. Different durations of R at the 6th h, orc. Different durations of R at the 8th hBatches (12) from each treatment then given 10min R interruptions over rest of the dark period

Link to module learning outcomes3. Carry out critical reflection on your own professional progress and plan for future professional development over the long, medium and short term. 4. Actively contribute to a community of practice 5. Demonstrate engagement with professional ethics and values espoused by the University and Professional Bodies, regarding inter-alia inclusivity, quality assurance and enhancement

Lessons learned
Good at collaboration
Crucial importance of functioning communities of practice
Responsibility as supervisor
Not very good at writing up for publication!

The University
a place for the communication and circulation of thought, by means of personal intercourse, through a wide extent of country (Newman, 1854)
