Certified small grain seed is warranted to have at least a 90 percent germination rate (80 percent for rye); nevertheless, it is a good idea to do a specific germination test on seed to be planted. There is no question that the germination should be checked on seed that is not certified or seed that is carried over from a previous year.<\/p>\n\n\n\n<p>Official tests require a minimum of 8 replications of 50 seeds each and are conducted over 7 to 10 days, depending on the grain being tested. The test can be extended 2 days for grain types that are slow to germinate. Growers can do a simple germination test at home. The procedure below does not pre-chill or pre-dry the seed as required for official seed certification standards, but provides some basic guidance on germination testing for the purpose of adjusting planting rate to achieve desired plant stands.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Simple at-home germination test<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>\n<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright is-resized\"><a href=\"https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"290\" height=\"300\" src=\"https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-290x300.jpg\" alt=\"seeds sprouting on a paper towel\" class=\"wp-image-12541\" style=\"width:370px\" srcset=\"https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-290x300.jpg 290w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-768x793.jpg 768w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-991x1024.jpg 991w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-105x108.jpg 105w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-317x327.jpg 317w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-423x437.jpg 423w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-634x655.jpg 634w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-846x874.jpg 846w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-951x982.jpg 951w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds-32x32.jpg 32w, https:\/\/extension.umaine.edu\/publications\/wp-content\/uploads\/sites\/52\/2013\/04\/seeds.jpg 1000w\" sizes=\"auto, (max-width: 320px) 85vw, (max-width: 768px) 67vw, (max-width: 1024px) 62vw,290px\" \/><\/a><figcaption class=\"wp-element-caption\">23 of 25 barley seeds germinating after 7 days [(23\/25)*100 = 92% germination] (Click on the image to view an enlargement.)<\/figcaption><\/figure><\/div>\n\n\n<p>\nCollect a <strong>representative<\/strong> sample of seed.\n<\/p>\n\n\n\n<li>Lay a paper towel out flat and, using a spray bottle, thoroughly moisten the paper towel, but not to the extent that water is running off it.
