110 CORN 



few windows and the temperature is usually so high that mold or 

 germination often results. 



Corn which has been dried thoroughly need not be moved from 

 the granary or loft because of cold weather. But to be safe, seed 

 so stored is better placed in the attic when the lower temperature of 

 winter comes on. On the ordinary farm, the seed corn store room 

 or separate building has not come to be a permanent fixture. When 

 much seed is sold, such a building is almost necessary. 



THE EFFECT OF MOISTURE AND FREEZING UPON THE 

 VITALITY OF CORN 



The purpose of this experiment was to determine just what efifect 

 freezing would have upon corn which was air dry and that containing 

 different percentages of moisture. 



Ears 1-5 were soaked in water at ordinary temperatures for five 

 hours. 



Ears 6-10 6 hours 



Ears 11-15 7 hours 



Ears x6-20 8 hours 



Ears 21-25 5 hours 



Ears 26-30 6 hours 



Ears 31-35 7 hours 



Ears 36-40 8 hours 



Immediately after being taken from the water, the ears numbering 

 I to 20 were placed in a refrigerator plant where the temperature 

 varied from 12 to 20 degrees Fahrenheit above zero. Here they were 

 left for 76 hours. Ears 21-30 were left under ordinary room tempera- 

 tures for ^2 hours and were then frozen for 24 hours. Ears 31-40 

 were not frozen at all, but ^^ere left in a room at 70 degrees Fahren- 

 heit. 



*The kernels were afterward taken from, each ear and analyzed for 

 moisture as well as given a germination test. The following table 

 shows the average percentage of moisture and the percentage of 

 germination before and after the treatment, with the consequent loss 

 in vitality.
