Conductivity changes for control and clubroot-infected plants at different soil packing densities. Measurements were made daily after inoculation for pots packed at 90 (Density 1) (a) and 105 (Density 2) (b) mg/cm3. Average values across the VOI and its standard deviation within the VOI are shown for the entire pot (0–13 cm), the upper section (6.5–13 cm) and lower section (0–6.5 cm) and the entire (0–13 cm) pot. Results are normalised to Day 0 for each replicate
