For several years now the Botanical Garden <strong>of</strong> the Polish Academy <strong>of</strong> Sciences in Powsin has<br />
been doing experiments on in vitro culture <strong>of</strong> Lilium martagon (Rybczynski and Gomolinska,<br />
1989) and ferns with simultaneous application <strong>of</strong> cryopreservation methods by using LN (liquid<br />
nitrogen).<br />
A seed bank is traditionally used for storing seeds <strong>of</strong> agricultural and horticultural plants trees and<br />
bushes at temperatures between +l0 o C and -20 o C. While the seeds are stored under those<br />
conditions, certain deterioration processes take place, which eventually influence the viability <strong>of</strong><br />
the seed material. The scientific and research potential <strong>of</strong> the Botanical Garden in Powsin helps<br />
to develop methods <strong>of</strong> seed preservation in ultra-low temperatures <strong>of</strong> liquid nitrogen, i.e. -192 o C.<br />
At present, there are being preserved in LN the seeds <strong>of</strong> some protected, endangered and extinct<br />
Polish native species which are on the red list <strong>of</strong> endangered vascular plant species. The research<br />
was focused on the introduction <strong>of</strong> several species <strong>of</strong> the following families: Caryophyllaceae,<br />
Cruciferae, Compositae, Gentianaceae, Labiatae, Liliaceae, Linaceae, Poaceae,<br />
Polentoniaceae, Rutaceae and Scrophulariaceae.<br />
