## 3 Results and Discussion  
The first parameter analysed throughout the growth period of sunflower, cress, and radish seed sprouts is the germination parameter. The results obtained for radish sprouts clearly show the tendency to accelerate the seed germination process during the first period of germination. After this period has elapsed, the number of germinated seeds in the control samples is equal to the number in the samples stimulated by two selected exposure doses of pulsating magnetic fields (Figure 3). The improvement of the germination process has been of interest to many authors. The factor improving this parameter was described by [PERSON] et al. [27]. They indicated that the exposure of passion fruit seeds to a sublime magnetic field in an isolated manner stimulates seed germination, emergence, and vigour. In another text of the authors [28], they demonstrated that chickpea seeds (_Cicer arietinum_ L.) subjected to magnetic treatment showed an improvement in seed germination efficiency in terms of the speed and length of the sprouts and the dry matter content of the seedling, and that the reaction varied depending on the intensity of the field and exposure time. The same positive effect on the rate of seed germination and vigour index was found in cucumber seeds (Cucumis sativus L. Var. [PERSON]) [29], lettuce (_Lactuca sativa_ L.) [30], \begin{table}

MST/32) [32], and radish seeds [33; 34]. Similar results of improvement in germination capacity are seen in trials of growth enhancement effects caused by plasma irradiation of atmospheric air dielectric discharge and thermal shock with radish sprout seeds (_Raphanus sativus_ L.). Interactions between radicals and seeds over a short time period of 3 min lead to an enhancement of the growth of radish sprouts over the long period of 7 days, and the maximum average length is 3.7 times larger than in the case of the control. The growth enhancement effects gradually weaken over time, therefore the ratio of mean duration of plasma irradiation to control irradiation decreases from 3.7 on the first day to 1.3 within seven days. The average length of the thermal shock of 60 \({}^{\circ}\)C for 10 min and 100 \({}^{\circ}\)C for 3 min is longer than in the case of the control, and the maximum average length is 1.3 times longer than in the case of the control. Thermal shock contributes little to the increase due to plasma irradiation because the maximum temperature due to plasma irradiation is less than 60 \({}^{\circ}\)C [35]. The results obtained for sunflower sprouts (Figure 4) clearly show the tendency to accelerate the seed germination process for almost the entire germination period up to day 12. After this point, the control samples have the same number of germinated seeds as the samples stimulated by the two selected exposure doses of pulsating magnetic fields. The study [36] shows the results obtained in terms of the effect of treating sunflower seeds subjected to accelerated ageing and cold test on seed vigour.
