Title
Phloem‐specific resistance in Brassica oleracea against the whitefly Aleyrodes proletella
Colette Broekgaarden; Pierre Riviere; Greet Steenhuis; et al. Entomologia Experimentalis et Applicata 2012. doi:10.1111/j.1570-7458.2011.01210.x
Other claims from this paper (5)
- Association Differences between the two cultivars are mainly due to antibiosis rather than antixenosis.
- Association Laboratory choice tests showed little or no discrimination between the two cultivars based on plant volatiles.
- Association Resistance increased during plant development and depended on plant age.
- Association Resistance was mainly independent of environmental factors.
- Association The resistance trait affects whitefly probing behaviour at the phloem level.
