EXERCISE 10 



GOOD GERMINATION 



Object. To determine which ears will germinate strongly. 



Material. Germination box, cloths, sawdust, ten ears of corn for 

 each student. 



Indications of Germinating Power. Let each student take ten ears; 

 the instructor should see that students have both poor and good ears. Ears 

 should be numbered 1-100. Describe each ear, using the descriptive terms 

 in Productive Farm Crops, page 65. 



Preparing Germination Box. See directions in Productive Farm Crops, 

 Chapter VIII. (Fig. 13.) 



Starting the Test. Let each student take six kernels from each of his 

 ten ears. In removing kernels take two from near the butt on opposite sides 

 of the ear, two from the middle, two from near the tip, turning the ear enough 

 so as not to take two kernels out of the same row. Place the kernels from 

 each ear in the square having the same number. If the box is kept in a warm 

 room, results follow in 5 or 6 days, if proper moisture is maintained. 



Results of the Test. The first three columns in the following table 

 should be filled out when the test starts; the remaining four columns at the 

 conclusion of the test.
