THE ONE HUNDRED‐YEAR PERIOD FOR DR. BEAL'S SEED VIABILITY EXPERIMENT

Abstract

After 100 years of burial in moist well aerated sand, 21 seeds of Verbascum blattaria , one seed of Verbascum thapsus and one seed of Malva rotundifolia , germinated and produced normal plants. Six additional seeds, of the original 50 seeds of each of 20 varieties, germinated and died before identification was possible.
