“The greater weight of the embryos of the large seed should be 
associated with the greater weight of mature plants, as noted in a 
preceding table. It seemed also desirable to correlate the matter of 
greater weight with that of the relative sizes of embryos; con- 
sequently there is added another table showing their measurements.

“Beginning with the first day after germination, and continuing 
for five days, it was found that the embryos of large seeds have 
wider and longer leaves than those of small seeds, while the embryos 
of medium-sized seeds are of intermediate dimensions. If plants 
are larger from their start, and even before germination, it is to 
be expected that they will continue to prove superior in size as they 
develop. 
“Observations have shown that radishes grown from large seed 
attain the edible stage sooner than those grown from small seed. 
Jt was thought that on this account they might contain more water ; 
hence a number of plants were trimmed as for eating and their dry- 
matter contents determined:
