Title

Other claims from this paper (10)
- Association Resistant cultivars of both crops often had reduced growth and development at high pathogen inoculum concentrations.
- Association Napa cabbage leaf length was 22% lower at a high-spore site in 2015.
- Association Resistant canola plant height was 30% lower at the high-spore site in 2014.
- Association Resistant canola biomass was 43% lower at the high-spore site in 2014.
- Association Resistant canola maturity was delayed at the high-spore site in 2014.
- Observation No differences among sites were found in 2015.
- Association At high spore concentrations in a growth room, resistant canola height declined by 12–14%.
- Association Canola biomass was lower with increasing spore concentration in some studies.
- Association Canola maturity was delayed with increasing spore concentration in some studies.
- Mechanism The authors suggest that expression of clubroot resistance can reduce growth and development in both crops, with substantial reductions only above 106 resting spores per gram of soil.
