Abstract An experiment was carried out aboard the Salyut 6 research orbital station on Arabidopsis thaliana cultivations. The seeds were sprouted in the Svetoblok 1 device which provides for plant growth in the agar medium under sterile conditions and at 4000 lux illumination. The experimental plants, as well as the controls, reached approximately the same developmental stages: both flowered and began to bear fruit. A microscopic examination of the generative organs in the control and experimental plants shows that in normally formed (by appearance) flower buds and flowers of the experimental plants, as distinct from the controls, there were no fertile elements of the adroecium and gynoecium. Degeneration of the latter occurred at different stages of generative organ development. Possible reasons for this phenomenon in plants grown under weightless conditions are considered.
