FLAX SEED 13 



cent, of moisture. A given quantity of air-dried flax seed in 

 capsules, germinated 100 per cent, five months after pulling. 

 (See Fig. 42.) 



12. Purity. The purity of flax or other seed is represented 

 by its known or ascertained percentage of pickles in any given 

 quantity of the specified seed, and this is easily obtained by 

 counting off all the flax or other specified seed present in any 

 given quantity 



EXAMPLE 1. In a given quantity of 300 seeds, say, 24 

 are grass, weed or other foreign seeds, and broken flax seeds. 

 Then the percentage of impurity would be 



24 X 100 



= 8% and .-. 92% purity. 



13. Relative Solving Value. The relative value of flax seed 

 for sowing purposes is a compound of the product of its ger- 

 mination and purity, e.g., if the germination is 80 per cent, 

 and the purity of the seed is 92 per cent., then the relative 

 value of the given seed in terms per cent, is equivalent to TOD 

 part of the product, thus 



% purity X % germination 

 100 



92 X 80 



.-. Relative value = = 7 31' 6% 



EXAMPLE 2. A quantity of flax seed germinated 90 per 

 cent, and its purity was also 90 per cent. Ascertain the 

 relative value of this seed 



1. Percentage value of germination 



100 90 



= T x i= 90 % 



2. The percentage value when the purity is 90 per cent. 



90 90 



14. Testing Flax Seed for Germination Value. This value of 

 flax and other seed is usually expressed in terms per cent.
