PURCHASERS' GUARANTEE 



The standard fixed for sugar-beet seed is known as 

 the "Magdeburger Normen" and seed growers gen- 

 erally guarantee their seed to be up to this standard, 

 which is as follows : 



(1) Dry substance, 85 per cent., that is, not over 15 per cent, 

 moisture. If over 15 per cent, and not exceeding 17 per cent, 

 moisture, deduction in price must be made for the missing dry 

 substance. If over 1 7 per cent, moisture, seed can be rejected. 



(2) Seed shall be 96 per cent, pure, that is, 96 per cent, of seed 

 balls which will not pass through a 2-mm. slit sieve, but seed of 

 94.5 per cent, purity is furnishable if the purity below 96 per cent. 

 is allowed for at its proportion of the purchase price. If less 

 than 94.5 per cent, pure, seed can be rejected. 



(3) Germination power must be, per kilogram (2.2 lb.): 



(a) In case of large seed-ball seed, 60,000 germs; 



(b) In case of medium seed-ball seed, 65,000 germs; 



(c) In case of small seed-ball seed, 70,000 germs. 



At least 70 per cent, of the required germs must have germi- 

 nated within seven days. 



The germination from 100 seed-balls within fourteen days 

 must be not less than: 



(a) In case of large seed-ball seed 80 seed-balls; 

 (6) In case of medium seed-ball seed 75 seed-balls; 

 (c} In case of small seed-ball seed 70 seed-balls.
