Seed treatment with "Trisol" stimulative products– seed germination impact
Šerá, Božena ; Hájková, M.
The seeds of barley (Hordeum vulgare L. RESPEKT) have been tested for stimulation effect of preparations originated in the BEIDEA company. Growth experiments were performed in sandy substrate, with 2 cm and 4 cm sowing, and under controlled conditions. Seed development, growth and dry weight of under- and aboveground seedlings were monitored. All preparations had a positive effect on the seed development and growth. Growth stimulatory effect is discussed in the text.

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.
