Lettuce lodging

Lactuca sativa L.

For lettuce, lodging is not a standardized agronomic metric. The term is more commonly applied in the context of pathological seedling damping-off or physiological impairment of stem integrity in hydroponic systems.

In the reference 28 varieties crop Lettuce, where this is mentioned in the description.

In lettuce agronomy, the term lodging does not refer to the assessment of adult plant stability; rather, it typically indicates seedling mortality caused by pathogens. For example, Rhizoctonia infection leads to the thinning and blackening of the hypocotyl, resulting in the wilting and falling over of seedlings.

Issues regarding stem structural integrity are primarily investigated in hydroponic systems, where silicon is used to strengthen tissues, or through instrumental measurements of stem strength. In breeding and official variety trials, this trait lacks quantitative scales or units of measurement.
