Ryegrass Warm Germination
Germination tests of perennial ryegrass are unique, in that annual and off-type ryegrass contamination is common and cannot be determined by looking at the seed. Annual ryegrass seedlings fluoresce under a black light, thus allowing one to separate this contamination and calculate the true germination percentage of perennial ryegrass.
This test requires wax paper, a special germination towel, the seed to be tested, and a blacklight.
The germination paper is covered with wax paper and rolled up.
The roll is labeled for identification, and two rolled up tests are held together with a rubber band.
The rolls are covered with a plastic bag and placed in the germination temperature at the correct temperature, relative humidity, and light.
