“…The progress of germination was measured every 24 h by registering the emergence of the radicle, until no more seeds germinated. To quantify the germinated seeds properly, the method described by Será et al (2008) was used. The mean germination time (MGT) was calculated following the procedure of Sadeghi et al (2011) (Eq.…”

“…Food/seed disinfection studies Selcuk et al 2008) and seed germination/seed viability studies (Será et al 2008;Zhou et al 2011;Dubinov et al 2000) were carried out using different plasma sources that create different concentrations of plasma reactive species, charged particles, and photons. Their approach for studying seed decontamination contained artificially inoculated pathogens on different food surfaces, which were exposed to CAP.…”

Sustaining the quality of seeds is a major task in attempting to supply nutrition to the growing world population. In this study, the seeds of Cicer arietinum were exposed to cold atmospheric plasma (CAP). A significant reduction of the natural microbiota attached to the seed surface was observed for increasing CAP treatment times-2 and 5 min were sufficient to achieve a 1 and 2 log reductions, respectively. Furthermore a 1 min CAP treatment showed a strongly improved seed germination (89.2 %), speed of germination (7.1±0.1 seeds/day), and increased seed vigor, beside a decrease in the mean germination time (2.7 days) compared with controls. The roughness profile of the seed cotyledon was altered significantly, only in case of longer treatment times from 5 min. These results suggest that CAP technology has the potentiality to reduce health risks associated with contaminated seeds, while improving food quality.

“…Cold plasma technology produced by dielectric barrier discharge (DBD) is a fast, cost-effective, and pollution-free method that can improve the germination performance of seeds and, consequently, the productivity of the crops (SELCUK; ORSUZ; BASARAN , 2008;SERÁ et al, 2008). In this sense, studies have been conducted with various species, such as: Oryza sativa (CHEN; CHEN; CHANG, 2012), Glycine max (LING et al, 2014), Leucaena leucocephala (GUIMARÃES et al, 2015) and Phaseolus vulgaris (BORMASHENKO et al, 2015).…”

-Plasma technology is a fast, cost-effective, and pollution-free method that can be used in place of conventional methods to overcome seed dormancy. The goal of the present study was to determine the effect of different application times of atmospheric plasma on soaking and germination of Hybanthus calceolaria seeds in order to accelerate these processes. Helium plasma jet produced by dielectric barrier discharge was used to treat H. calceolaria seeds with applications of 1, 5, and 10 minutes. The treated seeds were characterized considering their weight variation during soaking, changes in electrical conductivity, and pH. It was found that germination depended on the plasma application time. The treatment of H. calceolaria seeds with atmospheric plasma for 1 minute provided 3.5 times greater germination in comparison to untreated seeds. Atmospheric plasma technology obtained by dielectric barrier discharge had potential of being used as a germination accelerant in H. calceolaria seeds. The treatment of H. calceolaria seeds using atmospheric plasma for 1 minute favored germination.

“…There are many results, which indicate positive effects of the LTP on seed germination (increase germinating power of seeds and reduction germinating time), as well as on development, growth, enzyme activity and yield of plants (Volin et al 2000;Yin et al 2005;Marinković & Borcean 2009;Šerá et al 2008). The effective consequence of plasma treatment is also sterilization and destruction of microflora occurrence on the surface of plant seeds (Basaran et al 2008;Jung et al 2010).…”

Growth, anatomy and enzyme activity changes in maize roots induced by treatment of seeds with low-temperature plasma

et al. 2012

Abstract:The seeds of Zea mays L. cv. KWS were exposed to low-temperature plasma (LTP) by using Diffuse Coplanar Surface Barrier Discharge (DCSBD) for 60 and 120 seconds respectively. Growth parameters, anatomy of roots and activity of some enzymes (CAT, G-POX, SOD and DHO) isolated from roots grown from the seeds treated by LTP were evaluated. Our results indicate that LTP treatment of maize seeds affects post-germination growth of seedlings and this effect depends on the duration of LTP treatment. LTP treatment in duration of 60 seconds significantly increased the length, fresh and dry weight of the roots. However, the increase in time of LTP treatment to 120 seconds had inhibitive effect on the studied growth parameters. The activities of all studied antioxidant enzymes significantly increased with the age of maize seedlings in control conditions. On the other hand the application of LTP resulted in small, mostly non significant changes in the activity of antioxidant enzymes. Significant decrease in CAT activity was observed both in 3 and 6-day old maize roots and G-POX activity in 3-day old maize roots grown from seeds exposed to LTP for 60 seconds. A small, significant increase was detected only in SOD activity in 3-day old maize roots grown from seeds treated with LTP for 120 seconds and in 6-day old maize roots treated with LTP for 60 seconds. Significantly higher DHO activity was determined in embryos isolated from seeds treated with LTP for 60 seconds. On the contrary, in roots the DHO activity decreased with the time of LTP treatment. LTP treatment of seeds did not affect the anatomy of maize roots and caused only minor changes in the isoenzyme composition of G-POX and SOD.
