SEEDING AND PLANTING 





36. The Utilization Value of Tree Seed 



Until recently the utilization value of tree seed has been expressed 

 by the product obtained by multiplying the purity by the germi- 

 native capacity and dividing by 100. As a specific example, white 

 pine seed having a purity of 95.8 per cent and a germinative 

 capacity of 82 per cent has under this interpretation a utilization 

 value represented as follows: 



TTJ ... ,. purity X germinative capacity 

 Utilization value = - 



or Utilization value 



95.8 X 82 

 100 



78.6.
