Effects of the light treatment on the likelihood of a subset of capsules to produce seeds in Epilobium angustifolium. Dark: plants exposed on dark control sites; illuminated: plants exposed on illuminated sites; adjacent: plants exposed on a dark site but adjacent to the illuminated site (N = 240). Mean of model predicted values ± 95% confidence interval, as well as significance levels P ≤ 0.1 are shown.
