Hi folks,
   In the small grains, this is called preharvest sprouting.  It's
well-understood, and as Mary suggests is the result of lack of seed dormancy
and a wet harvest environment.  Calling it vivipary won't improve
understanding of the process.  In both barley and wheat the genetics of
dormancy and of preharvest sprouting is pretty well-understood.  
Cheers,
Tom Blake, barley breeder, Montana State University

Is there going to be consideration of the related process, dormancy?
