DISCUSSION AND INTERPRETATION OF RESULTS 
When Table V is examined certain regularities stand qut quite 
clearly. Thus, the acid-amide nitrogen rises fairly rapidly from 
0.50 per cent in the ungerminated seed (Nos. 31 and 32) to 2.85, 
6.17, and 8.46 per cent (Nos. 17 to 22), respectively, after 2, 4, and 
8 days of germination, calculated on the basis of the total nitrogen. 
This is also true of the uspulun-treated seed, which after 4 days of
