In which of the following Polyembryony is commonly found

Key Points

• The occurrence of more than one embryo in a seed is referred to as polyembryony.
• It is commonly found in citrus fruits like lemon and orange.
• Ways of forming polyembryonic seeds:
  • Developing of cells like synergids, cells of the nucellus, cells of integument into the embryo.
  • Formation of more than one embryo sac in an ovule.
  • Formation of more than one egg in an embryo sac.

Additional Information

According to Webber, polyembryony is classified into three different types :

1. Cleavage Polyembryony: In the case of this type, a single fertilized egg gives rise to a number of embryos.
2. Simple polyembryony: In this type, a number of embryos develop as a result of the fertilization of several archegonia.
3. Rosette polyembryony: Additional embryos develop from the rosette cells in certain gymnosperms, this type of polyembryony is termed rosette polyembryony.
