  My students in intro botany planted a sweet corn variety (Early
Sunglow, from Park Seed Co.) on Feb 15 in pots in the greenhouse. The plants
have had supplementary lighting from 6 am to 6pm. They are now producing
tassels, with stamens and anthers hanging down - but no sign at all of
ears! Not even swellings midway the stems where the ears usually appear.
  Does anyone have an explanation for this odd "behavior"? Could it be
a nutritional thing (there are 2 plants per gallon-size pot)?
