Variety traits

Vegetation period of lettuce

Lactuca sativa L.

The time interval from mass emergence to reaching technical maturity, limited by the onset of the bolting phase, after which leaf quality declines.

In the reference 232 varieties crop Lettuce, where this is mentioned in the description.

The vegetation period of lettuce is measured by the number of days from seedling emergence to the plant reaching specific biometric parameters, such as weight or rosette size. Harvesting is carried out before the crop enters the bolting phase, as leaves become coarse and develop a bitter taste once flowering begins.

The duration of the period varies significantly depending on the variety and growing conditions: early-maturing varieties ripen in 25–30 days, while late-maturing ones may require 70–90 days. High temperatures and long daylight hours accelerate development and force a reduction in the time frame for obtaining high-quality produce.

The crop demonstrates high sensitivity to agricultural practices: lack of moisture or overheating can inhibit biomass accumulation or trigger stress-induced flowering. The speed at which the vegetation period passes allows agronomists to use a succession planting method to ensure a continuous harvest.
