Hi Chris,
CG>        I am puzzled, not at the shoots in the grapefruit -
CG>        presumably if heat conditions follow a suitable pattern,
CG>        the seed will germinate - but at the presence of green
CG>        shoots within the fruit.
  The seedlings have already begun germination, and are green from
  chlorophyll stored in the seed itself. As far as I can determine,
  citrus shoots are never colourless, thus having to green up. They
  really are a "Sunny" fruit. :-)
CG>a week, although probably sitting on the store rack and perhaps
CG>in an open truck for many days before that.
  That doesn't seem to matter.
CG>Has anyone else ever discovered green shoots within a fruit?
  Sure. I have an ornamental (edible) miniature potted orange.
  Occasionally I will pluck and eat one of its tender-skinned but VERY
  sour fruits, and will sometimes crunch a seed. The seed is always
  green inside. Occasionally I plant an uncrunched seed, and the last
  one sprouted triplets - 3 shoots in 1. I separated them just to see
  what happens. :-)
                   ...Sandra...
