REPRODUCTIVE ORGANS OF PLANTS. 309 
1, That seed-wheat of the greatest density produces 
the densest seed. 
2. The seed-wheat of the greatest density yields the 
greatest amount of dressed corn. 
3. The seed-wheat of medium density generally gives 
the largest number of ears, but the ears are poorer than 
those of the densest seed. 
4, The seed-wheat of medium density generally pro- 
duces the largest number of fruiting plants. 
5. The seed-wheats which sink in water but float ina 
liquid having the specific gravity 1.247, are of very low _ 
value, yielding, on an average, but 34.4 lbs. of dressed 
grain for every 100 yielded by the densest seed. 
The densest grains are not, according to Church, always 
the largest. The seeds he experimented with ranged from 
sp. gr. 1.354 to 1.401.
