Variety traits
Tolerance in Lettuce
Lactuca sativa L.
Tolerance in lettuce is expressed as the ability of plants to maintain productivity and quality under abiotic stresses, such as high temperatures or substrate salinity.
In the reference 236 varieties crop Lettuce, where this is mentioned in the description.
Thermotolerance in lettuce is assessed by the ability of seeds to germinate at 30 °C and the resistance of adult plants to premature bolting and tipburn. Key indicators include the thermo-inhibition coefficient, germination rate, and scoring scales for internode elongation.
When assessing salinity tolerance, the effect of salt concentration on marketable leaf biomass, leaf surface area, and pigment content is measured. Lettuce is considered a moderately sensitive crop, which, under stress, typically exhibits a decrease in market quality and the development of bitterness in the leaves.
