Abstract

Germination of wild carrot (Daucus carota L.) was not confined to any season but was correlated with abundant soil moisture in field studies. In laboratory studies, germination percentage for any seed lot increased with time as dormancy was overcome. Further, the germination was not clearly correlated with seed weight, light, or pH, but temperature and the availability of water were clearly significant. Dormancy was due to the endosperm which surrounds the embryo. When part of the endosperm covering the tip of the radicle was digested or broken off, germination was increased nearly to the potential for a given lot of seed
