Davies, D. R.

The reproductive integrity of single meristematic cells of Tradescantia occidentalis exposed to acute doses of x rays was investigated. The dose response curve was sigmoid and similar to that reported for a variety of mammaliand cell lines having a D/sub O/ of 149 r and and extrapolation number of 1.6. Detailed observations were also made of all forms of chromatid and chromosome aberrations induced after irradiating all stages of the mitotic cycle of these same meristematic cells. Attempts were then made to correlate these two sets of data and to equate loss of genetic information to loss of reproductive integrity. (auth)
