  • Title: Cytogenetic analysis of seeds of Crepis capillaris (L) Wallr. exposed on board the earth artificial satellite Cosmos 613.

    Journal: Life Sci Space Res; 1976; 14():201-4. PubMed ID: 11977277.
    Abstract:
    We studied the effect of space flight factors on air-dry seeds of Crepis capillaris (L) Wallr. and on radiation injury of seeds exposed to gamma-radiation (3 kr, 525 r/min) before and after the flight on the satellite Cosmos 613. Space flight factors induced little increase (which was statistically insignificant) in the rate of chromosome aberrations in cells of the root meristem of Crepis capillaris sprouts, but they enhanced the effect of preliminary irradiation of seeds and decreased their radiosensitivity. The modification of radiation injury was statistically significant.
