The effect of plant density and growing season on leaf appearance rate (LAR)

			Rhythm ratio (period 2)
Season	LAR (period 1)	Rhythm ratio* (period 1)	D1	D2	D3	D4	Transition thermal time†
Spring	0·323	1	0·34	0·34	0·24	0·23	545 °Cd, GC 22
Autumn	0·219	1	0·66	0·37	0·23	0·22	950 °Cd, GC 25

* Ratio of LAR for each period to the LAR of period 1.

^† For each treatment, there was a point in time that LAR decreased, separating the whole growth period into two sub-periods – period 1 and period 2.

Note: D1, 1 plant m⁻²; D2, 3 plants m⁻²; D3, 6 plants m⁻²; D4, 11 plants m⁻².
