The germination capability of seeds was more reduced by the
combination of HP and carvacrol than when hypochlorite was
used. Thus, 80–93% of germination rate can be achieved using pressures
ranged between 100 and 250 MPa on seeds soaked in calcium
hypochlorite solutions, while the germination rates about 60–80%
were shown by seeds soaked in carvacrol solutions and treated at
these pressures, regardless of antimicrobial concentration in both
cases. It can be noticed that the increase of pressure had a more
pronounced effect on seed viability that the concentration of the
antimicrobials, which had not significant impact on germination
rate when 200–300 MPa were applied. The germination reduction
could be related with changes in biochemical reactions and denaturation
of proteins included key enzymes induced by the HP (Linton
& Patterson, 2002).
