FIGURE 4.

Estimation of anthocyanin accumulation in Arabidopsis plants. Fourteen days-old Arabidopsis plants were treated by 0,1 mM CdCl₂, 3 mM H₂O₂, 200 mM, and 500 mM sucrose, known to stimulate anthocyanin accumulation. Plants were photographed after 3 days and images were analyzed by PlantSize. (A) Images of plants with different anthocyanin content. (B) Reverse correlation of Anthocyanin contents and HUE values of individual Arabidopsis plants (pixel numbers were used according to Figure 1B). (C,D) Average anthocyanin contents and average HUE values of treated plants. (E) Reverse correlation of average anthocyanin contents and HUE values. Bars on diagrams indicate standard deviation, ^∗shows significant differences to control tested by one-way ANOVA (p < 0.05).
