Abstract
Quantitative intraspecific variation of DNA per cell was established by means of biochemical, double wavelength microspectrophotometry and micro-densitometric analyses of root tips from 7 seed sources of Picea sitchensis (Bong.) Carr. Northern seed sources possessed more DNA per cell than southern provenances. This, perhaps, is an indication of DNA adaptability through plasticity resulting from changing environmental stress over the natural range.
