Synopsis

Synopsis

Seeding values can be compared more effectively when seed test results are expressed as the number of normal sprout-producing seeds planted per square foot at a 1 pound per acre seeding rate (Y) than when germination, purity, or “pure, live seed” is used as the measure for comparison. Y values differed markedly for seed lots of different species, for lots of different varieties, and for lots within varieties. Seed weight was the variable most strongly affecting the value of Y.
