The equivalent effect of X-rays of different wave-length on the chromosomes oftradesgantia

  • Published:
Journal of Genetics Aims and scope Submit manuscript

Summary

An experiment is described in which the number of chromosome fragments produced inTradescantia pollen grain divisions by a dose of 1500 r. of two radiations of λc 0.44 A. and λc 0.077 A. is compared. The mean numbers of chromosome bodies per cell are 8.27 and 8.16 respectively. The difference, 0.11, is less than its own standard error of 0.44.

I am very much indebted to Mr J. R. Clarkson for carrying out the irradiations and measurements in the Physics Department of the Royal Cancer Hospital, London.
