For grass that really can stand up to tough usage, choose Quick Action®. Quick Action® is a set of perennial ryegrass varieties unique to DLF. We developed them to establish faster, to be strong and deep-rooting, and to be highly stress-tolerant.
Our R&D teams developed Quick Action® from perennial ryegrass because it's a popular lawn species. Perennial ryegrass is known for its fast establishment and tolerance to wear. Quick Action® turns a great lawn grass into something special.
When we say that Quick Action® is stress-tolerant, we mean that it stands up to a range of tough conditions (low rainfall or attack by fungi and insects) better than ordinary lawn grass.
The advantages of Quick Action® are apparent from the start. Seeds germinate sooner, even when temperatures are cooler. The seeds become stronger seedlings that establish faster to give greater ground cover without stalling the growth of other species within your mixture.
Quick Action® is a useful component of any lawn mixture, whether for new lawns or the repair of existing lawns.
Quick Action®, available only from DLF, is a new type of lawn turf – a tetraploid perennial ryegrass. Quick Action® grass germinates faster than ordinary perennial ryegrass, has superb tolerance to stress, and establishes fast and strong even when temperatures in the soil are a chilly 3–5°C.
With Quick Action®, you get green ground cover even during the winter. during the most difficult period of the year. It's more tolerant of drought during the autumn and winter, and provides better resistance to troublesome diseases such as fusarium and red thread.
Quick Action® has excellent resistance to snow mould
Polyploidy – the term to describe plants with more than two sets of chromosomes – is common in the plant world. It occurs in wild species as well as cultivated ones, proving that nature finds multiple sets of chromosomes advantageous.
In its natural state, perennial ryegrass is diploid: it has two sets of chromosomes. By using a natural substance, our R&D teams have developed tetraploid varieties (four sets of chromosomes). The route to tetraploidy is long because first-generation plants produce a mixture of diploid and tetraploid shoots within the same plant.
To obtain plants that are 100% tetraploid, we have to go through a series of selections of individual shoots. Each step is tricky too. We have to count the number of chromosomes on each shoot so we can pick out the tetraploid ones. Since perennial ryegrass is an outbreeding species, a single plant is not enough to create a variety.
We need several to make a population that avoids inbreeding depression. And we have to prove that our selected tetraploid shoots perform better than their corresponding diploids.
This is where the success of our research programme is outstanding. Standard tetraploid forage varieties are much courser, exhibiting more open and abundant growth than diploids. However, our Quick Action® varieties are comparable to some of the best diploids. They're fine with very good density and short growth.
