Variety traits
Lolium perenne L.
An integral indicator of perennial ryegrass, reflecting seed germination energy for the formation of dense sod and the plant's ability to rapidly recover above-ground biomass after mowing or grazing.
In the reference 63 varieties crop Perennial ryegrass, where this is mentioned in the description.
For perennial ryegrass, vigor characterizes the ability of seedlings to overcome soil resistance during emergence, which is critical for the early formation of a competitive stand. During utilization, the indicator determines the rate of regrowth after each mowing or intense grazing pressure.
Vigor assessment is conducted using laboratory methods by counting the number of healthy sprouts within set timeframes or by determining their biomass. Indirect methods, such as electrical conductivity or accelerated aging tests, as well as field measurements of green mass yield after grazing, are also applied.
High vigor ensures rapid development of ryegrass in the sowing year, which allows for more effective weed suppression and the formation of long-lasting pastures. In agronomic practice, this trait serves as a key criterion for selecting varieties capable of producing the maximum number of cuts per season.
