Seed Coat Structural Differences that Influence Water Uptake and Seed Quality in Hard Seed Cotton1

Synopsis

Synopsis

Water enters the seed by an opening in the palisade layer at the chalazal end. In hard seed this opening is made impervious by a chalazal cap and a seal between the cap and the palisade layer. In water at 80° C. the cap and seal become permeable, water enters and the palisade layer swells. Water entering through seed coat breaks has a similar effect on the palisade layer adjoining the chalazal cap.
