Variety traits

Vigor — Kentucky bluegrass

Poa pratensis L.

A complex trait reflecting the speed of germination and establishment of initial stand in a crop characterized by extremely slow early development.

In the reference 35 varieties crop Kentucky bluegrass, where this is mentioned in the description.

Vigor in Kentucky bluegrass (Poa pratensis) is assessed through a combination of indicators: speed of emergence, morphometric parameters (root and shoot length), and the rate of stand canopy closure. In laboratory conditions, the calculation is often performed using the Seedling Vigor Index (SVI), which accounts for germination combined with shoot and root length during early development stages.

Due to the biological slow-growing nature of bluegrass in its first year, this trait is critical for the competitiveness of the crop. Varieties with higher vigor establish a closed turf faster, which reduces the need for weed control and shortens the period until the lawn or pasture is ready for full use. High vigor also correlates with the plant's ability to quickly vegetatively regenerate its rhizomatous system following damage.
