Vitamin C and Chromosome Number in Rosa

Abstract

I AM obliged to Prof. Heslop Harrison and his colleagues for correcting errors in my list of chromosome numbers and in his own. Dr. Melville and Dr. Pyke, however, now make it clear that the principle of vitamin–chromosome correlation, being founded on observations of roses throughout their range of distribution and throughout their range of chromosome numbers, is indeed a valid inference. They also make it clear that the existence of one correlation with vitamin content does not exclude the possibility of several others.
