 TABLE 6. Size of seed and period of rest. 



The failure of such relationship to be clearly apparent is probably 

 due more to deficient field data than to the actual absence of any such 

 relationship. 



The size of the seed and the germination percentage are closely 

 connected, as shown by Table 7. 



TABLE 7. Relation of size of seed to germination. 



The percentage of germination decreases with the increase in the 

 number of seed per pound with the decrease in size of the seed. 



8. Similarly, the length of cone has a perceptible effect upon the 

 quality of the seed, as shown in Table 8. 



TABLE 8. Relation between length of cones and germination. 



Thus it is fairly evident that seed from shorter cones possess a 

 lower germination percentage than seed from longer cones. 



9. Since the size of the cones goes hand in hand with the weight, 

 the following generalization may be made: The larger or heavier the 

 cones the larger is the seed, and the larger the seed the greater is the
