Question
How polyembryony can be commercially exploited?
✓

Answer

  1. Polyembryony is the development of more than one embryo inside the seed.
  2. When such polyembryonic seed germinate we get multiple seedlings from it.
  3. This condition increases the chances of survival of new plants.
  4. Nucellar embryos are genetically identical to parent plants hence we get uniform plants.
  5. In horticulture we can utilize these as rootstock for grafting, hence they have significant role in fruit breeding programmes e.g. Citrus, Mango.
