Mechanism Older rolled leaves had diminished photosynthetic efficiency underlying lower net assimilation.
Observation Nutrient effects on net assimilation and interactions with infection were small and rarely significant.

Other claims from this paper (19)

Observation Rape varieties differed in resistance to the injury.
Association Nursery conditions were inferred to strongly influence injury onset.
Association Accelerated seedling growth was inferred to promote injury.
Mechanism A higher top-root ratio was inferred to promote injury.
Association Aphis showed no observed relation to injury.
Association Seedling characters and field conditions were inferred to influence injury.
Intervention effect Early sowing controlled the injuries.
Intervention effect Early transplanting controlled the injuries.
Intervention effect Late culture increased injury.
Association Transplanting time influenced injury more than sowing time.
Intervention effect Nitrogen was inferred to promote injury, particularly ripening failure.
Intervention effect Potash was inferred to promote injury, particularly ripening failure.
Intervention effect Phosphorus was inferred to promote injury, particularly ripening failure.
Intervention effect Compost application effectively prevented injury.
Intervention effect Wood ash applied in fields was the most effective injury control.
Intervention effect Wood ash applied in nursery beds was somewhat beneficial.
Intervention effect Boron application in basic fertilizer, as top dressing, or by spraying controlled injury.
Mechanism The authors attributed much of the injury to plant boron deficiency affected by growth conditions.
Mechanism The authors attributed compost and wood ash benefits to their boron content.
