Climate conditions and leaf characteristics (order and age) for the photosynthetic measurements

Year Measurement date Tg (°C) PPF (mol m−2 d−1) Leaf order Mean leaf age (d)
2003 18–24 June 17·7 34·9 8th 13
15–25 July 18·5 25·3 11th 18
20–30 August 20·9 23·7 14th 17
11–15 September 19·1 22·0 15th 40
2004 23–28 June 18·1 36·9 9th 15
21–26 July 21·7 22·6 12th 14
21–23 August 21·9 31·3 13th 16
14–18 September 19·7 24·9 14th 31

Tg and PPF are the mean daily growth temperature and mean daily photosynthetic photon flux, respectively, in the 2 weeks prior to measurements. Leaf order was numbered from the first leaf after germination.
