TABLE V. 



Germination of Seed Wheat Soaked in Water, Then Treated in Hot Water. 



The delayed germination of the untreated seed was due to the fact 

 that it had not been soaked in water previous to putting it in the germi- 

 nator, hence it tooli some time to absorb sufficient moisture for germina- 

 tion. 



In the formalin treatment seed soaked three liours in water and then 

 treated a quarter-hour in an .18 per cent, solution of formalin, was not ma- 

 terially injured, there being but 7.5 per cent, less germination than from 

 the untreated. That soaked one hour in water and one hour in the 

 formalin solution showed slightly more injury than any of the others. 



I-'or the hot water treatment a temperature of 120 degrees F. was 

 chosen, on the supposition that though considerably lower than that used
