The films shows examples of techniques and technologies for extraction and cleaning of seeds from cones that easily release seeds and from cones that do not easily release seeds.
Aside from presenting devices used for each of these two technologies, the film discusses the basic conditions that must be meet in order to obtain high-quality sowing material.
In order to achieve satisfying results from extraction and cleaning of seeds, it is necessary to maintain a temperature and humidity regime of cones and seeds and also to secure them against mechanical damage – which is also shown in the film.
