Figure 3

Changes in the chlorophyll fluorescence parameters Fv/Fm (A) and Φ PSII (B) in flag leaves and exposed peduncles at different stages. Each data point in the figure represents the average and the standard deviation of at least 10 individually selected and analysed leaves. F v /F m : maximum PSII quantum yield; ΦPSII: effective PSII quantum yield. Stages 1-5 correspond (respectively) to the end of anthesis, the milk-development stage, the soft dough-development stage, the hard dough-development stage and the ripening stage.
