Lettuce Vigor
Lactuca sativa L.
An integral indicator of lettuce seed quality, determining their ability for uniform germination and intensive vegetative mass development at early stages.
In the reference 129 varieties crop Lettuce, where this is mentioned in the description.
To assess lettuce vigor, laboratory methods are employed, such as the slant test, which allows for the analysis of root development speed, and accelerated aging tests, which reveal seed resistance to adverse conditions. Modern breeding utilizes computer vision to measure the projected canopy area and seedling growth dynamics in mm²/day.
High vigor in lettuce is critical for commercial cultivation, as it enables uniform emergence and reduces the need for thinning. Plants with this trait close the canopy faster, which suppresses weeds, and demonstrate higher marketable yields due to active biomass accumulation.
General information about the subject — on the page Vigor.
