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.

In many countries, the traditional method of growing shallots from bulbs is replaced by direct seeding in the field or by planting seedlings. The availability of shallot seed with high parameters of the sowing value is an important condition for growing shallot in larger areas. It is possible thanks to the progress in breeding and introduction into cultivation of new cultivars that produce seed stalks and seed. Therefore, the aim of the present study was to evaluate the sowing value of seed of the true-breeding cultivar ‘Toto’, when this seed is obtained by planting steckling bulbs (bulb-to-seed method) and by using the seed-to-seed method. This study, conducted in the period 2010–2012, was to evaluate some important characteristics of the seed quality obtained by planting different diameter bulbs (20–60 mm, 4 fractions every 10 mm) in autumn and spring and from seedlings planted in summer (third 10-day period of July and first and third 10-day period August). The quality of shallot seed was evaluated taking into account the following parameters: 1000 seed weight (TSW), germination energy and capacity as well as vigour tests (seedling growth test and seedling growth rate test). Shallot cultivation method had a large effect on 1000 seed weight, but it only slightly affected germination capacity and vigour of seed obtained. Larger seeds were obtained from bulbs, regardless of their planting time, compared to the cultivation method involving planting seedlings in summer. The diameter of bulbs used for planting at autumn planting time proved to be an important factor for TSW, germination energy and the traits determining seed vigour. In the case of this planting time, seed obtained from large bulbs with a diameter of 40–60 mm was distinguished by the best quality. The study did not show such a correlation for seed derived from spring bulb planting.

The aim of the study was to examine the morphology, and selected aspects of biology (seed germination capacity, biomass productivity) of reed canary grass (Phalaris arundinacea L.) growing in two locations with different soil conditions near Wrocław. Habitat 1 was characterized by low to moderate contents of nutrients, slightly acidic pH, and low organic matter content in the soil, whereas habitat 2 had soil richer in nutrients, a neutral pH, and higher organic matter content. During the growing period, phytosociological relevés were taken and biometric measurements were performed. In controlled conditions, the germination rate and biomass productivity were estimated in the initial growth stage. The soil conditions that were more favorable for P. arundinacea growth (neutral pH, higher content of organic matter and nutrients) promoted its dominance, and substantially limited the occurrence of other taxa. The floristic composition in the less fertile habitat was considerably richer and the abundance of P. arundinacea was much lower in it, compared with the other location. Phalaris arundinacea plants growing on the nutrient-richer soil were higher and had longer leaf blades and panicles with a greater number of spikelets per panicle than specimens growing on the poorer soil. Seeds collected from plants growing on the more fertile soil exhibited greater germination capacity than seeds from plants originating from the poorer habitat. However, there were no differences in the quantity of biomass produced in the controlled conditions.

The problem in the cultivation of scorzonera is often poor, slow and non-uniform field emergence despite the use of seeds with high germination capacity for the sowing. The goal of the study was to determine the effect of pre-sowing laser stimulation of seeds on the germination, emergence and root yield of scorzonera. Seeds were irradiated with a He-Ne laser with wavelength of 632.4 nm. Two doses of laser beam irradiation were applied in terms of surface power density – 6 and 8 mW·cmˉ². Seeds were irradiated 1, 3 and 5 times, and the duration of each irradiation treatment was ca. 0.1 s. Seed treatment with laser light caused an increase of germination capacity, radicle length and dry weight of seedling, and an improvement of field emergence and only a partial increase of the total yield of roots. Depending on the irradiation dose applied, the germination capacity of the seeds increased by 1.5-13.2% in relation to the control. The most beneficial effect on the germination capacity and field emergence was that of the 5-time laser irradiation. Increase of total root yield as a result of pre-sowing seed irradiation was related with increased emergence.

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.

The effectiveness of hydrophobic synthetic polymers in reducing imbibitional chilling stress in germinating bean seeds was evaluated. Two technical polymers and three Polish snap bean cultivars were analysed. Polymers were applied in amounts corresponding to 3.5% of seed weight. In the imbibitional chilling tolerance test, the seeds were rolled up in wet filter paper and left at 5°C for 72 hours, after which they were germinated at 20°C. The seed imbibition rate, germination energy, germination capacity and mean germination time were determined. The poly-mer coatings applied formed a barrier which slowed down seed imbibition, but it also significantly reduced germination energy and led to a decrease in germination capacity. The extent to which imbibitional chilling stress was mitigated was determined by the type of the polymer applied and the bean genotype analysed.

Nasiona koniczyny białej średniolistnej odmiany Barda i wielkolistnej Cyma stymulowano wiązką lasera He-Ne, zmiennym polem magnetycznym oraz kombinacją światła lasera i pola magnetycznego. W badaniach laboratoryjnych określono: energię i zdolność kiełkowania oraz procentowy udział nasion normalnie i nienormalnie kiełkujących, twardych oraz porażonych przez choroby grzybowe. Proces kiełkowania prowadzono zgodnie z zaleceniami ISTA (2009) i Rozporządzenia Min. Roln. i Roz. Wsi (Dz. U. z dn. 28.01.2013 r.). Materiał siewny odmiany Barda charakteryzował się istotnie mniejszą energią kiełkowania oraz zawierał istotnie więcej nasion twardych a mniej nasion normalnie i nienormalnie kiełkujących w porównaniu z odmianą Cyma. Stymulacja elektromagnetyczna w kombinacji L+P istotnie zwiększała udział nasion normalnie kiełkujących u odmiany Barda, a u obu odmian zmniejszała udział nasion nienormalnie kiełkujących.
