Note to § 201.55 : To 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.
