Germination of Seed as Affected by Sulfuric Acid Treatment 301 



These results agree so closely that it is evident the treated seeds would 

 germinate as well when planted in the soil as they show in the laboratory 



tests. 



The lots of clover seed dealt with in Table 3 were from selected lines 

 that were being propagated by an experiment station* in its breeding 

 work. The seed of the different lots was grown in 19 10 and was threshed 

 from the plants after these were thoroughly and carefully cured. After 

 threshing, the seed was kept for a time in the laboratory, in ordinary 

 homeopathic vials, and later in paper envelopes. The action of sulfuric 

 acid on all of these lots of seed experimented with is shown; it cannot 

 be said, therefore, that only those lots showing beneficial results from acid 

 treatment have been singled out and presented.
