Film p.t.: „Późnojesienny i zimowy zbiór nasion, pozyskiwanych przed ich opadnięciem”
Late fall and winter seed harvesting, harvested before they are shed
The sowing value of seeds is in large part determined by choosing the right time for harvest, proper handling during harvest, storage and adaptation. The time for harvest and subsequent handling of seeds are strictly related to the biological properties of various tree species, the intended purpose of the seeds and the predicted time for sowing.
It is possible to specify three groups of seeds which require different actions during harvest:
• harvested before full maturity,
• harvested before shedding,
• harvested after shedding.
The film shows conditions related with harvesting of seeds before they are shed. This concerns seeds of pine, spruce and black alder. Seeds of these species can be harvested as soon as in late fall or in winter.
