Table 2

Negative control experiments: comparison of five experiments at four different temperatures by means of global Poisson test.

Each cell value indicates the number of non-germinated seeds out of 198 (six Petri dishes). 𝜒^2∗ = comparison between temperatures within the same experiment (critical value at P = .05: 𝜒² = 7.81). 𝜒^2∗∗ = comparison between experiments at the same temperature (critical value at P = .05: 𝜒² = 9.49).
