Summary
The ribosomal RNA cistron number has been determined in a number of environmentally induced genotrophs of the flax variety “Stormont Cirrus”. The large genotrophs and the plastic variety were shown to have approximately the same number of ribosomal RNA cistrons while the small genotrophs had a reduced number of cistrons. There was no correlation between ribosomal cistron number and either nuclear DNA content of the genotrophs or plant weight.
