What is Polyembryony in Plants?
Polyembryony is a phenomenon observed in some plants where multiple embryos develop from a single fertilized egg cell or multiple fertilized egg cells within the same seed. This results in the production of multiple offspring (seedlings) from a single seed. In several gymnosperms, polyembryony is so prevalent that it is considered a significant characteristic of this plant group.
In angiosperms (flowering plants), polyembryony is less common but still occurs in some species. For example, in citrus plants like oranges, multiple embryos can develop within a single seed.
Polyembryony – Types, Causes, and Importance
Polyembryony refers to the occurrence of multiple embryos developing within a single ovule, seed, or fertilized ovum, and it is observed in both animals and plants. Polyembryony can be influenced by environmental conditions and genetic factors. Environmental factors such as temperature, light, and nutrient availability can cause polyembryony in certain plant species. Polyembryony examples are seen in mango, citrus, and in gymnosperms.
Genetic factors, including specific gene mutations or variations, may also play a role in regulating polyembryony. In this article, we will look into the meaning, causes, types, examples, and significance of polyembryony.
