Fig. 2.

Impact of the different shading treatments on fruit temperature recorded on a sunny day (A) and a cloudy day (B). Data shown are means of temperature measurements made on four different plants per treatment during ripening of fruits of the sixth truss on 12 April (A) and 14 April (B) during expt 2. Copper–constantan thermocouples (0·2 mm) were inserted 2 mm into the upper exposed side of the fruits. Temperature measurements were made every minute and averaged every 30 min. SF-IL, shaded fruits and irradiated leaves; IF-IL, control, irradiated fruit and leaves; IF-SL, irradiated fruits and shaded leaves; SF-SL, total shading (fruits and leaves shaded).
