Figure 5. — Effect of light filtering by anthocyanic leaves of S. hirsuta on the germination of lettuce seeds. The experiment was performed twice: under exscinded leaves in greenhouse conditions (A) or under living plants in natural conditions in the field (B). Bars represent the mean ± SE (n ≥ 12). No significant differences were found between anthocyanic and acyanic leaves in the number of seeds germinated underneath in any of the two experiments (P > 0.05). Details of the ANOVA analysis for (A): df = 1, mean² = 2.186, F = 0.011, P = 0.917; for (B): df = 1, mean² = 1943.29, F = 2.0 and P = 0.167.
