Gives the approximate number of seeds per pound.
Six Week Grow-out Test
Most commonly used for determining the annuality of fluorescing Ryegrass seedlings. [Can also be used for detection of endophyte].
Determines the percentage of moisture content of seed. Must be submitted in a sealed plastic bag to be accurate.
The cold test simulates early spring field conditions by providing high moisture and low temperatures. It is the oldest and most extensively used vigor test method in the U.S.
Endophyte Kit Test
Determines the percentage of endophyte in 100 seeds using a Neotyphodium Kit Test. At present, this test has only been validated for Tall fescue and Ryegrass. However, other kinds of seeds can also be tested.
Endophyte Kit Test
Determines the percentage of endophyte in 100 tillers using a Neotyphodium Kit Test. At present, this test has only been validated for Tall fescue and Ryegrass. However, other kinds of seeds can also be tested.
