Radiobiological experiments with plant seeds aboard the biosatellite Kosmos 1887

Selection note: Curated as historical evidence context for plant-seed exposure and radiobiological investigation aboard Cosmos 1887, relevant to crop germplasm resilience methods.
Evidence boundary: The old experiment record was screened through metadata and abstract; dosimetry, controls, statistics, and modern applicability were not validated. It is historical experimental context, not crop-safety claim evidence.

Source-supplied abstract
The effects of spaceflight factors on the seeds of Arabidopsis thaliana and Crepis capillaris were studied provided with various protective measures: the seeds were located inside the satellite and in open space, protected with aluminium foil and also exposed without the foil cover. When the seeds were in open space without any protection, their viability was found to be suppressed; the survival rate and fertility of plants grown from these seeds were also diminished. An increase in the frequency of chromosome aberrations (CA) and in the number of multiple injuries was registered in this case. Experiments with the aluminium foil shielding showed a decrease in the suppression of the seeds' viability, but mutational changes were found to be even more increased, while the survival and fertility of the plants decreased. An increase in the thickness of shielding resulted in a decrease in the effects up to the level of the control, except for the effects connected with CA and fertility of the plants. Analysis of the results shows that these impairments can be ascribed to the action of single heavy charged particles (HCP). The seeds can be thus regarded as an integral biological 'dosimeter' which allows estimation of the total effects of radiation, ecological and biological factors.
