A brief historical overview of the discovery of sexuality in flowering plants (Angiosperms) is given. The former assumption that pictures on Assyrian and Babylonian buildings represent pollination activity has to be corrected by new archeological insights. Antiquity and the Middle Ages delivered no real progress in the knowledge of higher plant sexuality. Real progress is linked to the introduction of light microscopy and experimentation. Investigators such as N. Grew, J. Bobart and R. J. Camerarius provided new information on sex organs in plants. Countercurrents of opinion remained active, based on Aristotle’s and Theophrastus’s beliefs. J.G. Koelreuter and G.B. Amici made breakthroughs in the recognition of the equal role of the sexes in reproduction. Fusion of the sperm and egg nuclei was observed by E. Strasburger. Double fertilization was a multiple discovery by S. Navashin and L. Guignard. New strategies are making the sexual and fertilization processes amenable to genetic manipulation and biotechnology.

Embryo sac development in reciprocal crosses of winter, hexaploid: wheat (Triticum aestivum L. cultivar ‘Liwilla’) and triticale (xTriticosecale Wittm. strain CHD 464) was examined during the first five days after pollination. Double fertilization was found in both crosses. Embryos developed regularly, slower however in the wheat ♀ x triticale ♂ cross. Aberrant, polyploid (up to 24n) endosperm nuclei were formed through disturbed mitotic cycles in both crosses. They occurred more frequently in the wheat ♀ x x triticale ♂ cross. Also, an early desynchronization of nuclear divisions and an uneven distribution of endosperm nuclei were found in the latter cross. They were accompanied with delayed or not complete cellularization of endosperm and its degradation in some regions. These abnormalities are the possible cause of the severe kernel sterility in the wheat ♀ x triticale ♂ cross. In contrast, the reciprocal cross produced shrivelled but mostly viable kernels.
