THE VITALITY AND GERMINATION OF SEEDS. 



TABLE III. Retardation in germination due to injury caused by unfavorable climatic 



conditions. 



a After 62 hours. 



in order that the results of Tables I and II may be more readily and 

 f ully comprehended, it has been deemed advisable to summarize them 

 in another table. For this purpose the average percentages of germi- 

 nation of all of the different samples of seed have been determined for 

 each of the different places. From these average percentages of ger- 

 mination the deterioration in vitality, as shown by both the first and 

 second tests as given in Tables I and II, have been calculated, the ger- 

 mination of the controls serving as a basis for comparison. These 

 results furnish more trustworthv data as to the relative merits of the 

 different localities as places for storing seeds. Likewise the per- 

 centages of deterioration between the time of the first and the second 

 tests are shown in Table IV.
