Effect of cold and sucrose treatment on Fv/Fm (a-c) and anthocyanin content (d-f) in the jar1–1 and coi1–16 mutants 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 (a and d), or on agar without (b and e) or with (c and f) 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/Fm was 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
