Opis:: The presence of Alicyclobacillus acidoterrestris, a thermoacidophilic and spore-forming bacterium, in pasteurized acidic juices poses a serious problem for the processing industry. Therefore, the use of other more effective techniques, such as high hydrostatic pressure (HHP) and supercritical carbon dioxide (SCCD), is considered for preserving juices in order to inactivate these bacteria, while reducing the loss of nutrients and sensory quality of juices. On the other hand, HHP and SCCD when combined with a moderately elevated temperature can induce germination of bacterial spores, making them more vulnerable to inactivation. The spore germination can be also induced by nutrients, such as L-alanine or a mixture of asparagine, glucose, fructose and potassium ions (AGFK). The aim of this work was to determine whether applying activating agents: HHP, SCCD and nutrient germinants (L-alanine and the AGFK mixture), could influence the number of spores which start to germinate and how this affects the proteins involved in the spore germination. SDS-PAGE was used to resolve proteins isolated from the A. acidoterrestris spores. The results that were obtained indicate that the germination of A. acidoterrestris spores treated with HHP, SCCD and nutrient germinants reflect the number of spores which start to germinate. The SDS-PAGE data indicated changes in the level of selected proteins occurring when subjected to the germination activating factors as well as noticeable differences in those proteins' molecular weights.

Opis:: Germination of flax seeds (Linum usitatissimum L., cv. Szafir) at 5oC was enhanced by continuous white light, gibberellin A3 (GA3), kinetin and benzylaminopurine. GA3 and kinetin at physiological concentrations (10-8-10-6 M) improved significantly germination in darkness. Stimulatory effect of benzylaminopurine was visible only in the light. Almost no effect of zeatin and isopentenyladenine (2iP) on germination was observed. Possible causes of this differences were suggested.

Opis:: Fresh and stored beechnuts collected in 1992, 1995, 1998, 1999 and 2000 were tested for viability and in 1998, 1999 and 2000 also for germination. Germination parameters such as peakvalue, mean weekly germination (modified mean daily germination), germination capacity, and germination value (Czabator 1962) were calculated from the germination test data and these indicators were also used for comparing beechnut quality. The highest viability for pre-stored beechnuts occurred in 1998 (80%) and this increased by 4% when these seedlots were stored for 1.5 years. Viability of fresh beechnuts collected in 1992, 1995 and 1999 was 64, 73 and 77%, respectively. Viability of 1995-collected beechnuts decreased after 3 years storage. Germination of fresh seeds was only done for the 1998, 1999 and 2000 collections where the best germination occurred for the 1998 collection. Germination of beechnuts collected in 1992 and 1995 was significantly reduced after 3 and 6 years of storage, respectively, while beechnuts collected in 1998 and stored for 1.5 years germinated about 15% better than fresh seeds of the 1999 crop. The peakvalue, mean weekly germination and the time required for viable seeds to reach 80% germination showed that the 1998 crop had the highest, overall quality. Eighty percent of the viable seeds collected in 1998 germinated in 9-10 weeks while fresh beechnuts from 1999 needed nearly 13 weeks to germinate, as did beechnuts collected in 1992 and stored for 7 years. Besides the germination capacity the germination value seems to be the very good indicator for determining the quality of stored beechnuts.

Opis:: Porównywano wpływ trzech metod kondycjonowania: hydrokondycjonowania, kondycjonowania w solach mineralnych oraz osmokondycjonowania na kiełkowanie i wigor nasion fiołka ogrodowego w temperaturze 20, 30 i 35°C. Nasiona hydrokondycjonowano w ograniczonej ilości wody (600 i 700 μl H2O·g nasion-1, 2, 3 lub 4 dni), kondycjonowano w roztworze KNO3 (-1.5 MPa, 5 dni) oraz osmokondycjonowano w roztworach glikolu polietylenowego (-1,0, -1,25 lub -1,5 MPa PEG 8000, 7 dni) w temperaturze 15 lub 20°C. Oceniano kiełkowanie i wigor nasion niekondycjonowanych i kondycjonowanych. Na ogól hydro-kondycjonowanie negatywnie wpływało na szybkość kiełkowania, procent kiełkujących nasion oraz zdolność kiełkowania. Kondycjonowanie w roztworze KNO3 przyśpieszyło kiełkowanie nasion w temperaturze 20, 30 i 35°C, ale nie miało wpływu na procent nasion kiełkujących i zdolność kiełkowania. Osmokondycjonowanie nasion w roztworze PEG o potencjale osmotycznym -1.0 MPa w temperaturze 20°C nie tylko znacząco poprawiaáo wskaźniki wigoru w temperaturze 20, 30 i 35°C, ale również najkorzystniej z zastosowanych metod wpáywaáo na procent nasion kiełkujących w temperaturze 30 i 35°C i istotnie zwiększyło zdolność kiełkowania nasion w temperaturze 20 i 30°C.
Three seed priming techniques: hydropriming, halopriming and osmopriming, were compared for their effects on germination and vigour of pansy (Viola × wittrockiana Gams.) seeds at 20°C, 30°C and 35°C. Seeds were hydroprimed in the restricted volumes of water (600 and 700 μl H2O·g seed-1, 2, 3 or 4 days), haloprimed in KNO3 solution (-1.5 MPa, 5 days), and osmoprimed in polyethylene glycol solutions (-1.0, -1.25 or -1.5 MPa PEG 8000, 7 days) at 15°C or 20°C. Seed germination and vigour tests were performed for untreated and primed seeds. Generally, hydropriming negatively affected the speed of germination, the percentage of germinating seeds and germination capacity. Halopriming accelerated seed germination at 20°C, 30°C and 35°C but did not influence the percentage of germinating seeds and germination capacity. Osmopriming of seeds in PEG solution of osmotic potential –1.0 MPa at 20°C not only improved germination rates at 20°C, 30°C, and 35°C to the highest extent, but also increased percentage of germinating seeds at 30°C and 35°C most effectively and positively affected seed germination capacity at 20°C and 30°C.

Opis:: Different nutrient media (MS [Murashige and Skoog 1962]; QL [Quoirin and Lepoivre 1977] and WPM [Lloyd and McCown 1980]); plant growth regulators BA (benzil adenin), GA3 (gibberellic acid), IBA (indole-3-butyric-acid), NAA (naftalen acedic acid); and sucrose concentrations were studied to determine the in vitro culture effects on healthier and faster seedling development from mature lentisk (Pistacia lentiscus L.) seeds. After 28 days of culture, the percentage of germinated seeds was the highest (70%) in the full-strength MS medium. The cytokinin BA was superior to other tested treatments in terms of its ability to promote germination of lentisk seeds. When tested at different concentrations, sucrose gave the best results obtained at concentrations of 1–4%, whereas high concentrations (6 and 8%) mainly decreased germination rate and there was no a regular pattern for elongation of the aerial parts of plants. With this described protocol, on average 76.67% seeds germinated 4 weeks after culture. Developed seedlings were satisfactorily acclimatized in sterilized peat, soil and perlite containing compost, with high percentage survival viability was obtained 9 months after transfer to in vivo conditions (93.33%). The results obtained showed that the enriched full-strength MS medium supplemented with 1 mg L–1 BA and 3% sucrose induced homogeneous and healthy seedling development in a period of 4 to 8 weeks of culture.

Opis:: The use of genetic potential of forgotten plants such as grasspea and arugula is an appropriate strategy for increasing of plants tolerance to environmental stresses. Therefore, in this laboratory study the effects of different levels of osmotic (0, -2, -4, -6, -8, -10, -12 and -14 bar caused by PEG) and salinity (0, 50, 100, 150, 200, 250, 300 and 350 mmol induced by NaCl) stresses were evaluated on germination indices of grasspea and arugula in four separate experiments. Arugula showed a suitable tolerance to osmotic stress, so that its germination percentage and rate at treatment of -10 bar were similar to control. Arugula had 79% germination at osmotic level of -14 bar, but its germination rate at this level was 60% lower than control. In addition, its radicle length until -8 bar and radicle dry weight up to -14 bar were higher than control treatment. However, all levels of salinity stress particularly treatments of more than 100-150 mmol decreased the germination indices of arugula. Germination percentage of arugula in 150 and 200 mmol treatments was 22 and 56% lower than control treatment, respectively. Grasspea had partially suitable tolerance to osmotic stress until -6 bar, but then intensified the reducing trends of its germination indices and finally reached to zero at -14 bar treatment. Moreover, salinity stress especially treatments of higher than 100 mmol decreased all germination indices of grasspea. Overall, arugula was a more tolerant plant especially to osmotic stress; therefore this forgotten plant can be used in agronomic and breeding programs in areas affected by drought stress

Opis:: The present experiment was carried out in the period 2006–2008. The aim of this study was to determine the effect of aqueous soil extracts from the soil of a spring wheat monoculture on seed germination energy and capacity, the length of the first leaf and of the longest radicle as well as the number of radicles. Moreover, the content of 0-dihydroxyphenols in the soil was compared in the last year of the study. The soil used to prepare the solutions came from a field experiment established on medium heavy mixed rendzina soil. Spring wheat, cv. Zebra, was grown using plough tillage and two conservation tillage methods in the presence of undersown crops (red clover, Westerwolds ryegrass) and stubble crops (lacy phacelia, white mustard). Germination energy of the seeds watered with the soil extracts from the ploughed plots was significantly higher than this trait in the seeds watered with the extracts from the conservation tillage treatments with spring disking of the catch crops. Germination energy and capacity of spring wheat in the control treatment watered with distilled water were significantly higher compared to the other treatments under evaluation. Spring wheat watered with the aqueous extract prepared from the soil obtained from the plough tillage treatment produced a significantly longer first leaf compared to the treatments in which both conservation tillage methods had been used. The shortest leaf and the lowest number of radicles were produced by the seedlings watered with the soil extract from the treatment with the white clover stubble crop. Radicle length was not significantly differentiated by the soil extracts under consideration. The content of 0-dihydroxyphenols in the rendzina soil determined during the spring period was higher than that determined in the autumn. The content of 0-dihydroxyphenols in the soil was lower in the conservation tillage treatments with autumn incorporation of the catch crops than in the plots in which plough tillage and conservation tillage with spring disking of the catch crops had been used. The type of catch crop used did not have a significant effect on the soil content of these compounds. At the same time, it was found that the treatments in which the catch crops had been sown tended to have higher contents of these compounds compared to the plots without catch crops.

Clarke) in the family Ericaceae using Na-dikegulac (Na-DK) for 8 hours (4 + 4 h in two installments) before keeping in ambient storage condition (32±2 ºC) for different durations (0 and 20 days) slowed down the rapid loss of germination and reduced the time (h) required for 50% seed germination (T50). Concomitantly, the reduction of protein level as well as the activity of catalase of seed kernels during storage period was ameliorated to a significant extent in the chemical pretreated seed lots.
