Cool and dry with a total temperature + relative humidity less than 100
How long do most grasses store well for before declining?
6 to 8 years
What should be the maximum percentage of inert matter in most grass seeds?
<15%
What is included in the total viable seed percentage?
% germination + % hard and/or dormant seed
What does the '100' rule of thumb for storage state?
(Temperature (F) + relative humidity (%)) <100 is ideal for storage
How long can hard-seeded species like legumes retain good viability under proper storage?
For decades
What does the '100' rule of thumb for storage state?
The sum of temperature (F) and relative humidity (%) should be less than 100 for best storage.
What does the term 'purity' refer to in seed quality?
The percentage of the seed lot that is free from inert matter, weed seeds, and other crop seeds.
What is the purpose of the Tetrazolium chloride test (TZ) in seed quality assessment?
To determine the viability of non-germinated seed by staining living seed tissues red.
