Fig 2. Direct and indirect plasma effects on germination rate of Arabidopsis thaliana seeds.

The boxplots show the effects of different applied plasmas on the testa rupture. Observations are made on four independent assays at t0+24h. Six hundred seeds are counted for each batch. Wilcoxon test has been used for the significance between the means, the p-value is: * < 0.05; ***<0.002 (For data see S1 Fig).
