Variations within a form-group do not necessarily come about by crossing two plants. There are indications that some of the traits that are passed on over generations are not mediated via the DNA of the cell nucleus. In Kultursaat, projects are also carried out with fundamental questions and investigations on such phenomena. It could, for example, be observed that the sound-treatment of seed with tone intervals can lead to changes in growth (leaf position, leaf shape, flowering time, etc.) and plant health in dandelion and lettuce. The influence of sowing dates, application of the biodynamic preps, and eurythmy (on soaked seeds as well as on the growing plant) and their influence on plant growth have also been researched.
