“…High hydrostatic pressure treatment has been studied as a new approach [9,[10][11][12][13][14][15]. Pressure is an important physical parameter on a par with temperature, but because pressure experiments are difficult to perform, the effectiveness of pressure treatment remains unclear.…”

“…Pressure is an important physical parameter on a par with temperature, but because pressure experiments are difficult to perform, the effectiveness of pressure treatment remains unclear. Nevertheless, high hydrostatic pressure treatment has several merits as compared to other methods: because pressure does not use disinfectants, it leaves no residue on the product [9,10,14], and whereas heat is distributed inhomogeneously and cannot easily reach the central parts of the seed, pressure reaches the inside of seeds homogeneously and instantaneously [16]. On the other hand, application of high hydrostatic pressure to seeds influences germination ability [9,14,15].…”

“…Therefore, prior to evaluating the effect of pressure on reducing microbial counts, we need to examine the effects of high hydrostatic pressure and temperature on germination percentage and germination time. These parameters have been studied widely for spores [17][18][19][20][21][22], but rarely for seeds [9,14,15]. In particular, to the best of our knowledge, the effect of high hydrostatic pressure on seed germination at low temperature (4˚C, typical refrigerator temperature) has not been investigated.…”

The effects of hydrostatic pressure (0.1 -400 MPa) and temperature (4˚C, 25˚C, and 35˚C) on the germination of three types of seeds (garden cress, leaf mustard, and radish) were studied. The normal germination rate of the three types of seeds was decreased at high hydrostatic pressure, and germination time tended to be delayed. Pressure and temperature had two types of effects on seed germination. Germination of garden cress and leaf mustard seeds was more resistant to pressure at lower temperature. Conversely, germination of radish seeds was most pressure-sensitive at low temperature, and germination drastically decreased with treatment at 50 MPa and 4˚C. Generally, pressure and temperature effects on protein structure and enzyme activity have been classified into two types, "hillside"-like (pressurization decreases the stable temperature range) and "tongue"-like (stabilizing effect of moderate pressure against heat denaturation). Therefore, the type of temperature-pressure effects on germination of garden cress and leaf mustard seeds is classified as "hillside"-like and that of radish seeds is classified as "tongue"-like, similarly to the generally observed effects on protein denaturation.

“…In this regard, the focus also shifted on the biological and nutritional quality of plant germs (Gabrovská et al 2005;Peñas et al 2008). Germination is influenced by the enzyme activity, while the level of activation of individual enzymes depends on the chemical composition of seeds, e.g.…”

The content of saccharides and lipids in wheat seeds from both conventional and organic agriculture was determined based on the length of germination (0, 2, or 5 days) and germination temperature (10 and 22°C). The content of saccharides was determined by HPLC, and the total lipid content was detected by Soxhlet extraction in the course of germination. While the non-germinated seeds had the highest content of glucose (6.95 mg/g) and fructose (4.37 mg/g), in conventionally grown seeds sucrose (5.03 mg/g) and maltose (3.62 mg/g) were at the highest level. In organically and conventionally produced seeds the contents of fructose, glucose, and maltose increased due to germination. While the content of lipids increased in the seeds from organic production on the second day from 0.46 g/10 g to 0.51 g/10 g (at 10°C) and 0.64 g/10 g (at 22°C). Differences in the content of saccharides and lipids between seeds from organic and conventional agriculture were not unequivocally confirmed.
