Abstract

Differential germination of corn chamomile (Anthemis arvensis L.) achenes was associated with achene size. Germination increased with reduction in achene size. Lower germination of large achenes was caused by a physical restriction of embryo expansion rather than by chemical inhibition or the preventive entrance of water or oxygen through the pericarp. This physical restriction was caused by lignified portions of the pericarp surrounding the seed.
