(Retest shall be made in soil or a mixture of soil and sand);\n(e) When no two satisfactory tests are within tolerance.\nNote to § 201.55:\nTo find the maximum tolerated range, compute the average percentage of all 100 seed replicates of a given test, rounding off the result to the nearest whole number. The germination is found in the first two columns of the table. When the differences between highest and lowest replicates do not exceed the corresponding values found in the “4 replicates” column, no additional testing is required. However, if the differences exceed the values in the “4 replicates” column, retesting is necessary.","path":["Title 7—Agriculture","Subtitle B—Regulations of the Department of Agriculture","CHAPTER I—AGRICULTURAL MARKETING SERVICE (STANDARDS, INSPECTIONS, MARKETING PRACTICES), DEPARTMENT OF AGRICULTURE","SUBCHAPTER K—FEDERAL SEED ACT","PART 201—FEDERAL SEED ACT REQUIREMENTS"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-7.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:24:01Z","sha256":"4d42f09925d692504328a846cd5d53e1b3242e91866c624f63f44273f6a46f9b","source_id":"us-cfr","stale":true,"prev":"us/7-cfr-201.54","next":"us/7-cfr-201.55a"},"notice":"GroundRules: Original legal text.
