Comments 



Mehlquist: I am commenting with reference to your slide showing 

 increased tolerance with increased size of the chromosomes and/or cell 

 size. As you know, we tried some of our Delphinium hybrids along with 

 carnations planted directly in the gamma field at Brookhaven and found 

 that the Delphiniums were so sensitive that they were killed to the 

 ground with the dosage at which the carnations showed little effect. 

 Yet the Delphinium chromosomes are many times the size of carnation 

 chromosomes.
