The plants are small and compact - many can be grown in a small space. After 2 - 3 weeks there is a recognisable crop. The crop can be measured in a variety of different ways. In a given packet, the seed will be genetically uniform. Differences between experimental and control groups are likely to be due to differences in growing conditions.
Radish seedlings show epigeal germination.
The photosynthetic cotyledons can be compared with the first true leaves. The radish hypocotyl is useful experimental material for tropisms. With acknowledgements and thanks to Dr John Hewitson, Oundle School, Peterborough. This material is copyright protected. See copyright notice.
