Longevity and Dormancy in Seeds of Several Cool-Season Grasses and Legumes Buried in Soil1

  1. H. H. Rampton and
  2. Te May Ching2



Nine kinds of crop seeds were buried in the field at 1-, 2-, 3-, 5-, and 7-inch depths in Saran mesh bags to determine seed longevity and dormancy. Generally, persistence and viability were lowest at the 1-inch depth and increased with depth, with differential longevity among species. Seeds of perennial ryegrass declined in viability most rapidly; orchardgrass and chewings fescue lost their viability after three winters; Highland bentgrass and Oregon annual ryegrass retained considerable viability; and red clover was highest in viability.
