Film p.t.: „Zbiór i stratyfikacja skrzydlaków jesionu wyniosłego”
Harvesting and stratification of samara from European ash
Harvesting of samara from European ash can be carried out between October-November or August-September.
The samara harvested during August are still green and are unsuitable for storage, but are suitable for immediate sowing. The samara harvested in October-November when it is fully mature can be stored even for a long period of time.
In order to interrupt seed dormancy, they require at least 7-8-month-long stratification.
The film shows how ash seeds are harvested, prepared for storage and stratified.
Ash is a species with seeds that require long-term stratification, first with heat and then with cold. As such, its seeds undergo complex treatment before sowing. The film shows this complex stratification procedure which is worth analyzing if one hopes to successfully preserve ash seeds over a long period of time.
