Germination — Perennial Ryegrass
Lolium perenne L.
The germination of perennial ryegrass reflects the ability of seeds to sprout under temperature conditions of 20–30 °C. This indicator serves as the basis for calculating the seeding rate, which typically ranges from 2–4 million viable seeds per hectare.
In the reference 29 varieties crop Perennial ryegrass, where this is mentioned in the description.
For laboratory determination of perennial ryegrass seed germination, specific temperature regimes for sprouting in the 20–30 °C range have been established. Standard requirements for the sowing qualities of this crop's seeds stipulate a germination level of no less than 80–85%, depending on the category of the seed material.
Perennial ryegrass is characterized by high germination energy and the emergence of seedlings on the 5th–7th day under favorable conditions. When seeds are sown at a depth of more than 2–3 cm or at soil temperatures below 5–8 °C, germination rates decrease, which leads to sparse stands and uneven turf cover.
