Polyembryony is a unique form of asexual reproduction whereby multiple offspring are produced from a single egg or zygote. To use Craig et al.’s (1997) words, polyembryony is a paradoxical combination of two reproductive modes—sexual and asexual reproduction. Nevertheless, it has evolved and been maintained in a wide range of taxa, including rust fungi

ON A CASE OF POLYEMBRYONY IN PTEROCARYA FRAXINIFOLIA (JUGLANDACEAE) AND ON POLYEMBRYONY IN GENERAL*
Acta Botanica Neerlandica, 1969SUMMARY A case of twin nucelli in an ovule of Pterocarya fraxinifolia, originated from a cleavage of the nucellus primordium and presumably representing a hitherto unrecorded type of polyembryony in Juglandaceae, is discussed. The qualification of this category of polyembryony as “false polyembryony” according to the conventional classification of ...

Twenty-nine polyembryonic seeds were found among 26,000 tomato seeds. These gave rise to twin seedlings. Five of the polyembryonic seeds appeared as a "double" seed with two units joined at adjacent sides to form the seed. Five pairs of conjoined seedlings were found. In some pairs, one member was four or five times larger than its mate. All the mature

T H HE fact that an egg may, under certain conditions produce two or more embryos is perhaps no more remarkable than that an egg will form a single individual. The developmental factors involved in the production of the individual embryo must be the same in both cases.
