[Space flight effects on bioobjects flown on Cosmos-1514].
The effect of space flight factors, particularly radiation, on Artemia salina cysts, tobacco and rice seeds (embryos and caryopses) was investigated. Artemia salina cysts showed no significant deviations in response to this exposure. Minor changes in certain cyst groups were related to their packing, humidity and preirradiation level. Tobacco seeds exhibited a higher frequency of somatic and morphologic changes that were independent of their packing arrangement. Rice seeds developed no changes that could be associated with space flight effects. The changes seen are considered in relation to the radiation dose absorbed. The results obtained in different space experiments are discussed.
