The high germination percentages of the seed samples and the growth of the derived plantlets are the main criteria to assess the quality of seed batches. The seed quality can be evaluated by seed germination tests. In the Council Directive 2002/55/EC of 13 June 2002 on the marketing of vegetable seed is defined that cauliflower and broccoli seeds being sold must exhibit at least 70 % and 75% germination percentages, respectively. To test the germination percentage of small seed lots, a simple method can be performed to test their quality.
