Vegetation period — Durum wheat

Triticum durum Desf.

A key biological trait of Triticum durum that determines adaptability, yield, and grain quality, measured in days from emergence to full maturity or by the sum of active temperatures.

In the reference 42 varieties crop Durum wheat, where this is mentioned in the description.

For winter durum wheat, the vegetation period is 280–290 days. For spring durum wheat, its duration varies from 75 to 130 days, with breeding groups divided into medium-early (82–84 days), mid-season (86–89 days), and medium-late (91–94 days). The heading phase is considered the most reliable criterion for assessing the maturity group, as the interphase period from emergence to heading is characterized by less variability.

The duration of the vegetation period is positively correlated with yield potential due to an increase in leaf surface area. Extending the period until heading contributes to increased vitreousness, but it may negatively affect grain size. Since durum wheat is demanding regarding harvest timing, precise determination of the vegetation period is critically important to prevent losses during over-ripening and to reduce risks associated with weather stress or late-summer disease infections.
