The effect of treatment of low temperature atmospheric plasma generated between the electrodes (plasma type: GlidArc, time of exposition: 180 s) on the seeds germination, crop parameters and yield components of poppy seed (Papaver somniferum L., cultivars Major and Orfeus) was observed. Increased germination was observed in 3 of the 4 treated seed samples in comparison with the control sample. The number of growing plants was negatively influenced as well as yield. Cultivar Orpheus responded more sensitively to the plasma treatment than cultivar Major. A higher number of capsules harvested per plant was founded in 3 of the 4 field variants.

Different reaction of cultivars poppy seeds after nonthermal plasma treatment
Banulescu, G. ; Gajdová, Iveta ; Šerá, Božena ; Kuchtová, P. ; Šerý, M. ; Špatenka, P. ; Hnatiuc, E.
The influence of low-temperature atmospheric plasma treatment generated between the electrodes (GlidArc) on poppy seed growth was tested. Treatment times were 0 s, 180 s, 300 s, and 600 s. Working gas was air. We monitored germination and initial growth of two cultivars of poppy seeds (Papaver somniferum L., cultivars Major and Orfeus). The values of control measurements (exposure time 0 s) of the tested cultivars were different. Therefore we analysed both cultivars separately with adequate control during the data procesing. A positive influence was found mainly in the lengths of sprouts in cultivar Major (22 %, time 180 s). The number of germinated seeds was not affected by plasma treatment in both cultivars.

Effect of various plasma sources on seed growth. Laboratory experimen in Buckwheat
Šerá, Božena ; Gajdová, Iveta ; Čermák, M. ; Gavril, B. ; Hnatiuc, E. ; Kováčik, D. ; Kříha, V. ; Sláma, J. ; Šerý, M. ; Špatenka, P.
Germination and early growth of buckwheat (Fagopyrum aesculentum) after low-temperature plasma discharge treatment in air gas generated in various apparatus were tested. Three pretreatment times were used: 180 s, 300 s and 600 s. Number of germinating achene, length and weight of sprouts were measured. The data was analysed with two-way ANOVA. A significant influence of the type of plasma apparatus, time of exposure and combination of both factors were found. The positive effect on germination and early growth was observed after application of GlidArc plasma. The opposite effect of PDBV apparatus, which is characterized by plasma with a high power density, was observed. Shorter pre-treatment times for this apparatus must be therefore used.
