Polyembryony in plants

Some plants produce several embryos in the same ovule. This phenomenon is called polyembryony.

Polyembryony can occur due to various reasons: either there are several embryo sacs in the ovule, or in embryo sac are several ova. Sometimes an extra embryo develops from the unfertilized synergids, antipode, of the cells of the nucellus, integument.

For example, in a tangerine, along with normal embryo developing from the ovum, produces 20 embryos from the cells of the nucellus. Despite the large number of embryo formation, full development reaches only one (rarely 2, 3), damping all others.
