| 1 | New Physicochemical Treatment Method of Poppy Seeds for Agriculture and Food Industries显示文摘Poppy seeds(Papaver somniferum L.) are often attacked by various fungal diseases,and their field germination rate is low.The aim of this experiment was to increase the germination rate and growth of seedlings by modifying the poppy seeds using cold plasma discharge.The seeds were treated in a Plasonic AR-550-M under power of 500 W with argon gas flow of 50 mL/min,oxygen gas flow of 50 mL/min for diferent time durations in seconds(0,180,300,600,1800,3000,4200,and 5400).The seed germination rate and growth of the seedlings were recorded.Cold plasma positively afected the seed germination rate for time exposure between 180~3000 s.Seedling acceleration on the sixth day of the experiment showed the highest values at exposure 180~600 s.Cold plasma seems to be a good physicochemical way to modify seeds without chemical agronomical application. | Bozena ER Iveta GAJDOV Michal ER'Y Petr PATENKA | 2013 | Plasma Science and Technology2013，15，9： | 0 |
| 2 | Does Cold Plasma Affect Breaking Dormancy and Seed Germination? A Study on Seeds of Lamb's Quarters(Chenopodium album agg.)显示文摘Low-pressure discharge is applied for stimulation of germination of two seed lots of Lamb's Quarters(Chenopodium album agg.) with different starting germinations(17%,8%) and in different stages of dormancy.Different exposition durations with cold plasma treatment were applied.The variable of the ratio cumulative germination was calculated.The Richards' equation was used for curve-fitting and simulation of the growth curves.Population parameters,namely Vi-viability,Me-time,Qu-dispersion,and Sk-skewness,counted from the curves described the germination rate well.Significant differences among Qu confirmed the erratic dormancy and gradual germination of Lamb's Quarters.No difference in the Me parameter was found between two tested seed lots,and no interspecies characteristics were changed using low-pressure discharge. The results suggested that plasma treatment changed seed germination in Lamb's Quarters seeds. | Bozena ERA Michal ERY Vitězslav TRANAK Petr PATENKA Milan TICHY | 2009 | Plasma Science and Technology2009，11，6： | 5 |
| 3 | Germination of Chenopodium Album in Response to Microwave Plasma Treatment显示文摘The seeds of Lamb's Quarters(Chenopodium album agg.)were stimulated by low-pressure discharge.The tested seeds were exposed to plasma discharge for different time durations(from 6 minutes to 48 minutes).Germination tests were performed under specified laboratoryconditions during seven days in five identical and completely independent experiments.Significantdifferences between the control and plasma-treated seeds were observed.The treated seeds showedstructural changes on the surface of the seat coat.They germinated faster and their sproutaccretion on the first day of seed germination was longer.Germination rate for the untreatedseeds was 15% while it increased approximately three times(max 55%)for seeds treated byplasma from 12 minutes to 48 minutes. | Bo■ena ER Vitězslav STRA■K Michal ER■ Milan TICH■ Petr PATENKA | 2008 | Plasma Science and Technology2008，10，4： | 4 |
