Polyembryony is common in

Key Points

• Polyembryony refers to the occurrence of more than one embryo in a single seed.
• It is commonly observed in Citrus fruits, such as oranges and lemons.
• In Citrus, polyembryony often occurs due to the development of nucellar embryos along with the zygotic embryo.
• Polyembryony ensures the production of genetically uniform plants, which is beneficial for agriculture.

Important Points

• In plants exhibiting polyembryony, multiple embryos can develop from the same ovule, resulting in more plants from a single seed.
• Polyembryony can be classified into three types:
  • Simple polyembryony: Development of multiple embryos from a single zygote.
  • Adventive polyembryony: Development of embryos from somatic cells of the ovule (e.g., nucellar tissue).
  • Mixed polyembryony: Involves both zygotic and adventive embryos.

Additional Information

• Banana: Bananas are parthenocarpic fruits, meaning they develop without fertilization. They do not exhibit polyembryony.
• Tomato: Tomato plants reproduce sexually, and their seeds usually develop a single embryo. Polyembryony is not observed in tomatoes.
• Potato: Potatoes are propagated vegetatively through tubers. They do not involve seeds and hence do not exhibit polyembryony.
