Effect of cold and sucrose treatment on Fv/Fm(a-c) and anthocyanin content (d-f) in the晶澳r1–1andcoi1–16mutants and their respective wild types, Col-0 and Col-gl. The plants were grown at 20 °C (red bars) or 4 °C (blue bars) in compost (aandd), or on agar without (bande) or with (candf) addition of 55.5 mM sucrose. Individual leaves (leaf position 6) were analysed for compost-grown plants and whole shoots for agar plates. Compost-grown plants were harvested after 15 days of temperature treatment (age of plants 54 days) for anthocyanin analysis; agar-grown plants were harvested after 25 days of treatment (age of plants 38 days). Fv/Fmwas measured on the day before the harvest. Data are means of 5 plants (compost) or plants from 5 plates +SE. Temperature effects, genotype effects and interactions were analysed by two-way ANOVA. The asterisks indicate statistically significant differences between the 20 °C and 4 °C treatments for each genotype (Tukey’s HSD post-hoc test; *P < 0.05; **P < 0.01). To allow comparison of the anthocyanin contents on different growth media, the y-axis scaling is the same for all media
