4 CONTROL SERIES No. 80 



The letter "R" after the germination percentage in the table of vegetable 

 seeds indicates that the sample has received one or more retests. 



All lots of seed included in this report were tested according to the Rules for 

 Seed Testing adopted by the Association of Official Seed Analysts. 



"Tolerance" is applied to both purity and germination, except in those 

 tables which list seeds falling under sections of the law not requiring purity or 

 germination on the label. For the application of "Purity Tolerance", the 

 sample is considered as made up of two component parts: (1) the component 

 being considered, and (2) the balance of the sample. The tolerance in percent- 

 age allowed for each component shall be two-tenths of one per cent (0.2%) 

 plus twenty per cent (20%) of the lesser of the two parts. "Germination 

 Tolerance" has been applied between a given germination and the result of 

 the germination test as follows: 



Given Germination Allowable Variation (%) 



90 or over 6 



80 or over, but less than 90 7 



70 or over, but less than 80 8 



60 or over, but less than 70 9 



Less than 60 10
