RESULTS OF SEED TESTS 

 Made July 1, 1925 to June 30, 1926 



Four hundred and seven samples of seeds have been 

 tested for purity and germination this year. Three hun- 

 dred and sixty-nine of these have been completed for the 

 State Department of Agriculture on samples collected 

 more or less indiscriminately about the State for the 

 purpose of verifying their guarantees for purity and 

 germination, and of making sure that all seed sold in 

 New Hampshire carries such guarantees and other in- 

 formation on the container as are prescribed by law. 

 The results of this official work are shown in this bul- 

 letin. Samples submitted for private tests are not made 

 public. 



Biological response, or reaction, to natural, or arti- 

 ficial environment changes is subject to considerable 

 variation and the germination of seeds is no exception. 

 No two samples of the same seed will necessarily germ- 

 inate exactly alike either in a natural, well adapted soil 

 or under the best artificial conditions that science can 

 devise for the laboratory. Consequently, much duplica- 

 tion and great care in sampling and counting is nec- 

 essary to arrive at a satisfactory average figure. Under 

 the limitations of time and space necessarily imposed on 

 any laboratory procedure, it seems advisable to allow 

 considerable variation between any given set of findings 

 at any given time and place and those found elsewhere 

 at another time. Our inspection and investigation work 

 assumes that a given sample may manifest the following 

 variations from the guarantee which it carries for germ- 

 ination and still comply with the state law and support 

 the good intentions of the merchant who attached the 

 guarantees. This table is based on the research work of 

 the Association of Official Seed Analysts of North 

 America and is recommended in their rules.
