Effect of Environmental Factors on Germination and Emergence of Invasive Rumex confertus in Central Europe

Figure 6

Effect of concentration on cumulative germination of R. confertus seeds at 22°C for 20 days. Means () with the same letter do not differ among different KNO₃ concentrations with the same light conditions (ANOVA Tukey’s test, ). Error bars indicating standard deviations are shown only where it was larger than the point size.
