We may infer from this data that in these plants weight of seed and 
color of seed are correlated, and that the heavier seed in general-ger- 
minate better than do the light seed. 
A few trials were made of the germination of large and small seed, 
as compared with ordinary seed taken from the same package, result-

The influence of the position of the seed upon the plant has received 
apparently less study than its importance deserves. In experiments 
carried forward last year upon the butt, central and tip kernels of 
maize, the influence of position was extremely marked in favor of the 
greater crop capacity of the tip kernels. We have hence made a num- 
ber of trials of the germination properties of seed selected with reference 
to their position. In the corn trials the tip kernels were manifestly 
lighter in weight than either the butt or central kernels, while in the 
sorghum the tip seeds were the heavier. Thus —

Passing to our germination trials, we give the result in a table, 
which renders quite evident that the germinative vitality of the tip 
kernels are, in general, superior to that of the kernels in other positions. 
In germinating the seed the kernels were laid upon the surface of the 
sand in our apparatus ; in vegetation trials the seed was buried beneath 
the surface.
