Variety traits

Vegetation period — flax

Linum usitatissimum L.

The duration of flax ontogeny from emergence to maturity, measured in days, which determines cultivation strategy and cultivar selection.

In the reference 37 varieties crop Common flax, where this is mentioned in the description.

For fiber flax, the vegetation period is calculated up to the early yellow maturity stage and averages 70–90 days, shortening to 60–65 days during drought or extending to 100 days under conditions of excessive moisture. For oilseed flax, this period is longer and varies from 62 to more than 94 days depending on the earliness of the variety.

In breeding and cultivation, the duration of stages is recorded based on key phenophases: emergence, "herringbone" stage, rapid growth, budding, flowering, and ripening. The length of the vegetation period directly influences yield, resistance to climatic risks, and the planning of agrotechnical operations, including the timing of chemical applications.
