SEEDS AND SEED GROWING IOI 



done to determine the sprouting or germinating 1 quali- 

 ties of garden seeds. Sprouting tests are made in plates, 

 pans, dishes and in various apparatus where soil and 

 moisture conditions may be controlled to a greater or less 

 degree. Gardeners want to know whether their seeds will 

 grow when planted under real conditions, and germina- 

 tion tests are regarded more valuable by practical grow- 

 ers when carried on under natural conditions. Seeds are 

 counted in .lots of 25, 50, or better 100, and planted in 

 drills. The soil should be in good physical condition and 

 watered often enough to keep it moist. When sufficient 

 time has been allowed for germination, the plants in each 

 row are counted and the percentage determined. Such 

 a test may be the means of avoiding losses and disap- 

 pointments by sowing seed of low germinating power. 

 It requires very little time, and it is a great satisfaction to 

 make the main planting with the assurance that a High 

 percentage of the seed will grow. Most of the large seed 

 houses test the germinating power of their seeds before 

 supplying customers. 



Rules and regulations for official seed testing, adopted 

 by the standing committee on methods of seed testing df 

 the Association of American Colleges and Experiment 

 Stations, are published in Circular 34 of the Office of Ex- 

 periment Stations. 



The following table shows about the average percent- 

 ages of germination of one-year-old seed when planted 

 under proper conditions :
