Influence of high hydrostatic pressure treatment on licorice (Glycyrrhiza uralensis Fisch.) hard seeds germination

Abstract The effects of hydrostatic pressure (from 100 to 250 MPa with different exposure options) on the germination hard seeds licorice ( Glycyrrhiza uralensis Fisch.) were studied. Among used pressures, best result was obtained after three times by exposure. In this variant, good dynamics swelling and observed, proportion normal seedlings from total number in studied sample largest. It is shown that higher levels load led a decrease normally developed seedlings.
