Variety traits
Lettuce plant height
Lactuca sativa L.
An important biometric parameter of lettuce cultivars that determines planting density, harvesting methods, and the onset of the bolting phase.
In the reference 106 varieties crop Lettuce, where this is mentioned in the description.
When evaluating lettuce, plant height is measured from the soil surface to the apex or the growing point of the plant at the technical maturity stage. Leaf and butterhead varieties are characterized by a compact rosette, whereas Romaine-type varieties have an upright rosette, and stem lettuce is distinguished by significant stem height.
Changes in plant height serve as a technological indicator: excessive stem elongation due to unfavorable conditions or high temperatures indicates etiolation or an early transition to the flowering phase, which reduces market quality due to leaf toughening and the development of bitterness.
