Traditional turf type perennial ryegrasses (diploids) have two sets of chromosomes, whereas tetraploids have four sets. Forage tetraploid grasses have long been known for showing better stress tolerance and disease resistance compared to diploids and now these advantages have become available for turf grasses as 4turf and have been bred specifically by DLF Seeds & Science for rapid establishment and unique stress toleranc
4turf provides Ground Managers with a unique solution for improved grass cover during difficult seasons. The picture below shows the unique tolerance to winter fusarium after a hard winter in Denmark 2010/2011
In warmer climates 4turf shows better recovery from both
drought and heat stress.
below shows - Drought trial in Czech Republic showing
drought tolerance of 4turf varieties.
Rapid establishment enen under low soil temperatures
4turf seeds produce stronger seedlings with faster establishment at low temperatures making 4turf well suited for autumn and winter overseeding programs, resulting in fast establishment and excellent turf quality.
