Appendix A. Statistical table on the impact of distance from source and genotype on infection dynamics in a wind tunnel experiment.

Table A1. The impact of distance from source, source plant genotype and pathogen genotype on the infection dynamics on leaves from two receiving plant genotypes placed at several distances (5, 20, 40, 130 cm) in a wind tunnel experiment at a constant wind speed of 0.25 m/s.
